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: Gravitational Potential Energy | 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.

A ball is thrown vertically downward from a height of $$20$$ m with an initial velocity $$v_0$$. It collides with the ground, loses $$50\%$$ of its energy in a collision, and rebounds to the same height. The initial velocity $$v_0$$ is:
(Take, $$g=10~\mathrm{ms^{-2}}$$)
1. $$14$$ ms–1
2. $$20$$ ms–1
3. $$28$$ ms–1
4. $$10$$ ms–1
