Question

A particle is moving in a vertical circle. The tensions in the string when passing through two
positions at angles 30° and 60° from vertical (lowest position) are T, and T2 respectively, then​

Answer 1

2 2 0

v - u =2g(l+lsin0 )

=2gl(l+l/2)

=xgl(3/2)

2

v - 10gl =-3gl

2

v = -3gl+10gl

2

v = 7gl

T+mg cos
