Wats wrong wid this????

Experts this is very easy so please dont tell d answer.....but lets see

x+iy=0.....................1
x=-iy
x/y=-i
(x/y)2=(-i)2
(x/y)2=-1
x2=-y2
x=iy
==>x-iy=0....................2
arent one and 2 contradicting???? IS THERE ANY MISTAKE????

OHHHHH!!!
Manipal Then how u are applying them in case of planets???

Akand ·

yup......................
gow will u solve
S=10+102+103...........

here r is 10........so -1<r<1 is not valid over here............

SO I DO HAVE AN OBJECTION....

wats ur solution to this 1
do solve it u will get to know ur folly

POST UR SOLUTION[1]

waaaaah u should get a pink 4 it

do u agree with ur solution

One more misleading question...
According to Newtons law of gravitaion
F is inversely propotional to r...
But when ur forefinger and middle finger are in touch with each other , wont the force of attraction be infinity!! (1/0=∞),
Pls dont try to answer in mathematical sense - undefined..
U can say it is infinite in physics -sometimes(like timeperiod of pendulum)

newton law of gravitation is only valid 4 ponit charges

Guys my question is buried deep inside ur progressions.....someone point out the "correct" mistake...

11
Mani Pal Singh ·

MANIPAL.............its not r<1..........the condition is r≠1..........hehehe

@akand i said |r|<1
=> -1< r <1
so this is perfect

do u have any objection[7]

11
Mani Pal Singh ·

they r assumed to be point charges

remember shell theorem na!!!!!!!!!!!!!!!

1
sriraghav ·

Ok...Why not in this case?? Even ur fingers are solid structure like planets...U can apply the Gravitational law here!!

Mani Pal Singh ·

iska matlab tu kuch aur sunna chahta hai!!!!!!!!!!!!!

assertion 2
MASS OF FINGER IS VERY VERY VERY LESS[1]

sriraghav ·

Translation of first statement required....
Assertion 2 : Not exactly

:O

sriraghav... this is due to STRING THEORY :) :)

Mani Pal Singh ·

amrita ji yeh STRING THEORY kya hai????

1
sriraghav ·

STRING Theory????????????????????
One more new thing..K. cud u explain @skygirl

#8 But ppl. he is making mistake in first step itself rite?? dividing by 0..

he is not dividing it

Philip Calvert ·

ye kya kar rahe ho akand
last line kayde se root lo na......

either put | | or take ±

Mani Pal Singh ·

sorry akand
not fooled by it
x+iy=0.....................1
x=-iy
x/y=-i
(x/y)2=(-i)2
(x/y)2=-1
x2=-y2
x=iy

==>x-iy=0....................2

please explain me the bolded thing
i will explain u the contradiction!!!!![1]

I am adding one more misleading question.. Note only 11th graders are advised to do this Q., 12th graders pls be QUIET!! 11=1 22=2+2
"
"
"
x2=x+x+x+ ............. x times
Differentiating both sides.. u get 2x on LHS and 1+1+1+......x times on RHS therefore 2x=x 2=1.. But how this is possible?? K.. let x be less than or equal to 2 and greater than 0

1
Philip Calvert ·

in fact x & y both are zero sriraghav ....
so we can say that the question is in a mess......

or we can say that x/y exists "imaginarily" finitely

1
sriraghav ·

But ppl. he is making mistake in first step itself rite?? dividing by 0..

1
Akand ·

yes yes guys..........and sriraghav....hws 33=3+3+3??? and isnt this question ther in a forum

1
Akand ·

YES YES GUYSSSS...............u r very smart.............this was just for fun......

1
Akand ·

ok one more.............
Sn=1+1+1+1+1.....n
since this is a GP....
Sn=a/1-r
=1/1-1
=undefined.......
so 1+1+1+!= undefined?????? or is it n???? hehe

1
sriraghav ·

In sixth step.. u have to take both + and -.. and not only one thing.....and infirst step u said that it is equal to 0!! so imaginary part is zero.. so u cannot divide x by y(which is 0)..

1
sriraghav ·

Sn formula is only for infinite series Akand!!

sriraghav ·

K.. i hav edited the question, the mistake which leads is a very basic one...
