A rectangular block of size \( (b \times h) \) moving with velocity \( v_{0} \) enters on a rough surface where the coefficient of friction is \( \mu \) as shown in figure. Identify the correct statement.
(1) The net torque acting on the block about its COM is \( \mu \mathrm{mg} \frac{h}{2} \) (clockwise)
(2) The net torque acting on the block about its \( \mathrm{COM} \) is zero
(3) The net torque acting on the block about its \( \mathrm{COM} \) is in the anticlockwise sense
(4) None of the above
