Let the frictional force be f...

is the ans is
v=(2L/m(mg(sin@-ucos@)+BIL(cos@+usin@)))^1/2

Rohan Ghosh ·

is it solid or hollow?

any way if it is solid =

v= √[(4H/3sinθ)*(gsinθ+(ILBcosθ/m))]

if it is hollow =

v=√[(H/sinθ)*(gsinθ+(ILBcosθ/m))]

OOPS.. The radius of the cylinder is R

Rohan Ghosh ·

radius is not reqd

i just want to know whwther it is hollow or solid

Siddharth ·

u were very very close Rohan..

Answer is √[4gsinθ/3 + 2ilbcosθ/3][H/sinθ]

Rohan Ghosh ·

r u sure that is the answer

Siddharth ·

mostly bro.. I have done it twice.. i might be wrong too.. but i think it was worth a question....]
u might be right too bro... I must accept that ur really good at physics...

Rohan Ghosh ·

where is m in ur answer there should be m otherwise dimensionally it is not correct

1
Siddharth ·

there is an m below 2ilbsinθ

1
Rohan Ghosh ·

i think 2ilBcosθ

1
Siddharth ·

OOPS again... Well yes
Below 2ilbcosθ
LOL
