b)2
c)5
d)0​

Answer 1

Answer:

the net torque acting on a rotating body with uniform speed is

d) 0 ✔️✔️✔️✔️

Answer 2

Answer:

d) 0​

Explanation:

d) 0​

Consider mass to be constant. As a result, acceleration and torque are proportionate. Since acceleration is zero, we know this (definition of uniform velocity). Because of this, torque is zero.

The absence of any linear or angular acceleration implies that the net force and torque are equal to zero, which suggests equilibrium, if an item is spinning at a constant rate and moving with constant speed and direction.

The angular momentum is constant and hence preserved when a system experiences no torque. This is similar to the linear equivalent in that the momentum is conserved when there is no external force acting on the system.
