A paratrooper is falling down with uniform velocity and also rotating with a constant angular velocity of 0.2 rad/sec. The body satisfies _.

Explanation

First condition of equilibrium: The condition states that a body will be in equilibrium if the resultant of all the forces acting on it is zero. Sindh Textbook for Class XI P145 Second condition of equilibrium: The body is said to be in rotational equilibrium, if the vector sum of the torques acting on it is zero. This is second condition of equilibrium Sindh Textbook for Class XI P149 Body satisfies the first and second law of equilibrium. The first law states that for an object to be in equilibrium forces acting on it must be equal and opposite, since the paratrooper is falling with a uniform velocity, this means this is true. The angular velocity is also constant, which implies that torque acting on the paratrooper clockwise is equal to the torque acting anticlockwise.
