Question

The generalized equation of momentum $p=\frac{mv}{\sqrt{1-\frac{v^2}{c^2}}}$ comes from the fact that when a particle moves with high speed , then

• A. mass increases
• B. velocity varies
• C. time dilates
• D. particle nature changes to wave nature

Answer 1

The correct option is A mass increases

The generalized equation of momentum is given by
$p=\frac{mv}{\sqrt{(1-\frac{v^2}{c^2})}}$
comes from the fact that when a particle moves with high speed then its mass increases.
Relativistic mass is given as
$m=\frac{m_0}{\sqrt{(1-\frac{v^2}{c^2})}}$
where, all the variables have their usual meanings.
