A. Mass increases.
B. Mass decreases.
C. Mass remains constant.
D. Mass vanishes to zero when velocity equals half speed of light.

Answer:

option (A)

Explanation:

The a body having rest mass is mo is moving with velocity v which is of the order of velocity of light in vacuum, so the mass of the body increases. According to the formula

[tex]m=\frac{m_{0}}{\sqrt{1-\left ( \frac{v^{2}}{c^{2}} \right )}}[/tex]

As the velocity increases, the mass m of the body increases. As the velocity of the object is equal to the velocity of light in vacuum, then the mass of the body becomes infinite.
