Solution

The correct options are
B KE decreases
C PE increases
Since work is done in opposite to the conservative force. its potentiial energy increases and KE decreases as total mechanical enegy is conserved.
Therefore, B and C are correct option.

The work done by a force acting obliquely is given by the formula: W = $F c o s θ \times s .$ What will happen to the work done if angle $θ$ between the direction of force and motion of the body is increased gradually? Will, it increases, decrease or remain constant?

Q. A student says that he had applied a force

F = - k \sqrt{x}

on a particle and the particle moved in simple harmonic motion. He refuses to tell whether k is a constant or not. Assume that he was worked only with positive x and no other force acted on the particle.
(a) As x increases k increases.
(b) As x increases k decreases.
(c) As x increases k remains constant.
