What is the value for the kinetic energy for a n = 5 bohr orbit electron in zeptojoules?

The kinetic energy is 86.6 zepto joules.

Explanation:

Given that,

Number of orbit n =5

We know that,

Bohr's radius for hydrogen atom is

Now, put the value of n in the formula of radius

We need to calculate the kinetic energy

Using formula of kinetic energy

Put the value into the formula

We know that,

The kinetic energy is

Hence, The kinetic energy is 86.6 zepto joules.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
