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 Subtopic: Â Gravitational Potential Energy | Â 85% From NCERT NEET - 2022 To view explanation, please take trial in the course.

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.
