Question

In the given figure of square plate, possible axis of rotation is shown,if in each case we give same torque parallel to the axis shown then

• A. angular acceleration about 1 and 2 will be same
• B. angular acceleration about 2 and 4 will be same
• C. angular acceleration about 1 and 4 will be same
• D. none of the above

Answer 1

The correct option is B angular acceleration about 2 and 4 will be same

The axis $1$ & $3$ are symmetric. also, the axis $2$ & $4$ are symmetric. this implies angular acceleration about $2$ & $4$ is same.
