Question

A particle is moving with constant speed v in a vertical circle. The value of tension T will be maximum at point.
a) L
b) H
c) M
d)same at all points​

Answer 1

Answer:

same at all points

Explanation:

because the speed is constant

hope this helps

Answer 2

Tension is maximum at the point H

Explanation:

case 1 : when the body is at lowermost position (h=0)

   $T=m/r(u^2-3gh+gr)$

At point L, h=0

$T = m/r(u^2-3g(0)+gr)\\==> m/r(u^2+gr)$

case 2 : When the body is at higher position (h=2r)

$T = m/r(u^2-3gh+gr)$

At point H, h=2r

$T=m/r(u^2-3g(2r)+gr)\\==> m/r(u^2-5gr)$

Relationship between the tensions at the highest point and the lowest point

$mu^2/r+mg-mu^2/r+5mg\\==>6mg$

As a result the tension at lower point will be six times more than that of the tension at the higher point

Hence the tension will be maximum at point H
