Example 66: A charged particle shows an acceleration of

4.2 \times 10^{12} \mathrm{~cm} / \mathrm{sec}^{2}

under an electric field at low speed. Compute the acceleration of the particle under the same field when the speed has reached a value

2.88 \times 10^{10} \mathrm{~cm} / \mathrm{sec}

. The speed of light is

3.0 \times 10^{10} \mathrm{~cm} / \mathrm{sec}
