A particle of mass m is suspended from point O and undergoes circular motion in horizontal plane as conical pendulum as shown in figure.
Options:(select one or more)
Answer:
A, B, C, D
Solution:
About the suspension point, gravity exerts torque, so angular momentum is not constant.
About the circle centre, horizontal centripetal force gives zero torque and the vertical component is constant.
Impulse over half a turn gives average force 2mg tanθ/π.
The average torque about OC over a half rotation is zero.
