An object falls from a height of \(10~\text m\) above the ground. After striking the ground it loses \(50\%\) of its kinetic energy. The height up to which the object can re-bounce from the ground is:
1. \(7.5~\text m\) 2. \(10~\text m\)
3. \(2.5~\text m\) 4. \(5~\text m\)

A gravitational field is present in a region and a mass is shifted from \(A\) to \(B\) through different paths as shown. If \(W_1\), \(W_2\) and \(W_3\) represent the work done by the gravitational force along their respective paths, then:
1. \(W_1=W_2=W_3\) 2. \(W_1>W_2>W_3\)
3. \(W_1>W_3>W_2\) 4. \(W_1<W_2<W_3\)

A mass \(m\) is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when:

1. inclined at an angle of \(60^{\circ}\) from vertical.
2. the mass is at the highest point.
3. the wire is horizontal.
4. the mass is at the lowest point.
