Express in (or or if more appropriate):

a. The kinetic energy of a Li ++ ion that has accelerated from rest through a potential difference of .

b. The potential energy of two protons apart.

c. The kinetic energy, just before impact, of a ball dropped from a height of .

a. The potential energy of two protons is.

b. The potential energy of two protons is.

c. The kinetic energy just before impact is.

We have given that express in

We need to find the kinetic energy of a Li ++ ion that has accelerated from rest through a potential difference of

Ion has charge. As it is accelerated through the the total energy will be

We have given that express in

We need to find the potential energy of two protons apart.

Potential energy is given as

We have given that express in

We need to find the kinetic energy, just before impact, of a ball dropped from a height of n

The kinetic energy just before hitting the ground will be equal to the potential energy and is equal to . Here and .So energy will be
