Electrostatics

There are infinite equipotential lines all parallel to the line AB in a right angled triangular region ABC as shown.All points on the vertical line have the same potential and proportional to the length of the line.

(a)An electron kept at rest will move parallel to the vector

(i) CB (ii)BA (iii)CA (iv)will remain at rest

(b)If Ep Eq and Er denote the electric field at P,Q,R respectively then

Ep>Eq>Er (ii)Ep<Eq<Er (iii)Ep=Eq=Er (iv)none

(a) (i) CB

because the direction of Electric field at a point is perpendicular to the equipotential surface at that point

(b) (iii)

P,Q,R are on the horizontal line,not vertical

yaar woh connected to hai
tu to danda leker peeche hi pad gaya

ab

main paani pion ya paani mere dwara [pia jaya
baatto ek hi hai

waise hi p,q,r horizontal par bhi hain aur vertical pe bhi

why is this thing hard to digest 4 u [257]

they are not connected

that triangle is only the boundary line

p,q,r are on separate vertical lines who potentials are proportional to the lengths of the lines

NOW TEMME D POINT "A" HERE LIES IN VERTICAL OR HORIZONTAL LINE?????

are they on the same vertical line?

NOW THIS IS MY FINAL WORD REGARDING Q2

NOW IF U DONT CONSIDER THEM JOINT AND U THINK THAT THEY R DIFFRERENT THEM I AM SORRY 4 U
AND I DONT HAVE FURTHER EXPLANATIONS!!!!!!!!!!

sparkle seems to be right..

i dont knwo if I have gone crazy.. but ram and mani... isnt it given that the potential is directly prop to the height

and hence the potential at p,q,r are different!

phew..thanx !

If all the vertical lines are at same potential..and also those points on those horizontal lines...does any field exist?
