In which scenario is gravitational potential energy present? a rabbit looks out of a hole in the ground. a squirrel runs up the trunk of a tree. a deer runs across a grassy field. a cat pins a mouse to the ground.

Option (b) is the correct answer.

Explanation:

Gravitational potential energy is the energy possessed by an object due to its position on the surface of Earth or in a gravitational field.

Basically gravitational energy is the gravitational pull acted by the earth.

Thus, we can conclude that out of the given options, a squirrel runs up the trunk of a tree is a scenario in which gravitational potential energy is present.

A squirrel runs up the trunk of a tree.

Explanation:

A body possesses gravitational potential energy due to virtue of its position i.e. height. It is given by:

G.P.E = m g h

where, m is the mass, g is the acceleration due to gravity and h is the height.

It is measured in Joules.

A squirrel runs up the trunk of a tree converts kinetic energy to gravitational potential energy. At the top, it possesses only gravitational potential energy when it is a rest. Thus, it is a situation where gravitational potential energy is present.

A rabbit is on the ground, a deer runs on a grassy field and a cat pins a mouse to the ground- These are not the examples of gravitational potential energy.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
