This set of Engineering Physics Multiple Choice Questions & Answers (MCQs) focuses on “Einstein’s Special Theory of Relativity”.

1. As an object approaches the speed of light, it’s mass becomes _____________

a) Zero

b) Double

c) Remains Same

d) Infinite

View Answer

Answer: d

Explanation: We know, for an object in motion m=[Math Processing Error]

Thus, as v = c, the quantity in denominator becomes zero. Hence the mass of the object becomes infinite.

2. If the sun radiates energy at the rate of 4 x 1026 Js-1, what is the rate at which its mass is decreasing?

a) 5.54 x 109 kgs-1

b) 4.44 x 109 kgs-1

c) 3.44 x 109 kgs-1

d) 2.44 x 109 kgs-1
