An electron is accelerated through 100 kV. By what factor has its mass increased with respect to its rest mass?
A)1.20
B)1.55
C)4.25
D)6.50
E)8.00

Question

Quizplus · Accepted Answer

The relativistic mass increase can be calculated using the formula $ m = m_0 / \sqrt{1 - v^2/c^2} $. For an electron accelerated through 100 kV, its velocity becomes significant compared to the speed of light, leading to a mass increase factor of approximately 1.20.
