Question

an object of mass 5 kg is released to a height 4m above the ground what is its potential energy?​

Answer 1

Required Answer:-

Potential energy is the energy possessed by a body in virtue of its position and its configuration. According to position, it is given by:

$\large{ \cdot{ \underline{ \boxed{ \sf{E_p = mgh}}}}}$

Where,

• Ep = Potential energy
• m = mass of the body
• g = gravity
• h = height of the body.

Here, we have m = 5 kg, h = 4 m and assuming that the body was released to earth, g = 9.8 m/s².

Plugging the values,

➙ Ep = 5 × 4 × 9.8 joules

➙ Ep = 196 joules.

Hence:-

Potential energy of the body at a height 4 m is 196 joules. This can also be called as gravitational potential energy.

Answer 2

Answer:

m=5kg, h=4m, g=10m/s^2

potential energy=mgh

=5×10×4

=200joule
