Question

Fill in the blanks :

The mass of a body remains constant till the velocity of body is ............

• A. much less than the velocity of light
• B. equal to velocity of light
• C. much higher than the velocity of light
• D. none of the above

Answer 1

The correct option is A much less than the velocity of light

According to Einstein if a body moves almost more than the velocity of light then it starts losing its mass.He gave this concept by a formula that is $E=m{c}^2$.Hence for the body to maintain constant mass it has to move with the speed less than the velocity of light.
