Assertion : When the speed of an electron increases its specific charge decreases.
\( P \)
Reason : Specific charge is the ratio of the mass
W. to charge.
(1) A
(2) B
(3) \( \mathrm{C} \)
(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
(C) Assertion is correct, but reason is wrong statement.
(D) Assertion is wrong, but reason is correct statement.
