Teaching Rajasthan 3rd Grade REET Mains (Level I & II) Mock Test Physics Gravitation Gravitational potential energy
Four balls are undergoing free fall as mentioned below:
(a) a 2 kg ball from a height of 5 cm
(b) a 2 kg ball from a height of 120 cm
(c) a 3 kg ball from a height of 120 cm
(d) a 3 kg ball from a height of 80 cm
Rank the gravitational potential energies of these four objects in the ascending order.
1
a > b > c = d
2
a < b = d < c
3
a > b > d > c
4
a < b = c = d
