11.Dual Nature of Radiation and matter
easy
Assertion : If the speed of charged particle increases both the mass as well as charge increases.
Reason : If $m_0 =$ rest mass and $m$ be mass at velocity $v$ then $m = \frac{{{m_0}}}{{\sqrt {1 - \frac{{{v^2}}}{{{c^2}}}} }}$ where $c =$ speed of light
A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
If the Assertion is incorrect but the Reason is correct.
(AIIMS-2000)
Solution
When speed of particle increases, the mass increases as $m = \frac{{{m_0}}}{{\sqrt {1 – \frac{{{v^2}}}{{{c^2}}}} }}$ charge does not alter
