Question

A proton has a mass 1.67*10^(-27) kg and charge +

Answer 1

The kinetic energy is 1.6 x 10^-14 J

Explanation:

A proton had a mass of 1.67 ?10^-27 kg and charge +1.6 ?10^-19C. If the proton is accelerated through a potential difference if a million volts, then the kinetic energy is?

Initially the proton is at rest so kinetic enerfy is zero

Total energy = Kinetic energy + Potential energy

Thus the potential energy at rest moment.

• Potential energy = q x v

                            = 1.6 x 10^-19 C x 1 x 10^6 V

When the proton is accelerated it has gained Kinetic energy.

T.E = K.E + PE

• Kinetic Energy = 1/2 mv^2

• As both are equal so

K.E = qv = 1.6 x 10^-19 C x 1 x 10^6 V = 1.6 x 10^-13 J
