calculate the potential energy stored in a meta ball of mass of 80 kg kept at a height of 15m from the earth surface . What will be the potential energy when the metal ball is kept on the earth surface Take (g- 9.8 m/s] ​

11760 J

Explanation:

cuz potential engery is PE = MHG

SO 80×15×9.8= 11760 J

11769j

Explanation:

here,

mass(m)=80 kg

height(h)=15m

acceleration due to gravity(g)=9.8m/s^2

now,

potential energy = m×g×h

= 80×9.8×15

= 11760j

im sorry i dont know

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
