A spool is pulled horizontally on rough ...


A spool is pulled horizontally on rough surface by two equal and opposite forces as shown in the figure. Which of the following statements are correct?

A

The centre of mass moves towards left

B

the centre of mass moves towrads right

C

the centre of mass remains stationary

D

The net torque about the centre of mass of the spool is zero.

Text Solution

Verified by Experts

Net torque about bottommost point is clockwise. Hence, the spool will move towards right.
