When a body of mass 2.0 kg is suspended by a spring, the spring is stretched if the body is pulled down slightly and released, it oscillates up and down. What force is passes through the mean position?

Since there is no acceleration in the body at the mean position, hence the resultant force on it will be zero, i.e., the force applied by the spring will be exactly equal to the weight of the body.
