Abox of mass 3kg is lifted 1.5m onto a shelf. calculate the change in its gravitational potential energy. the gravitational field strength is 10n/kg.

The change in gravitational potential energy is 45 J.

Explanation:

Given that,

Mass = 3 kg

Distance = 1.5 m

Gravitational field strength = 10 N/kg

We need to calculate the change in gravitational potential energy

Using formula of  gravitational potential energy

Put the value into the formula

Hence, The change in gravitational potential energy is 45 J.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
