Answers
To find: The equation for calculating the fractional increase in mass of the particle for a given velocity of 0.1c.
Solution:
m = m0/[1-v^2/c^2]^1/2
(m0 = the rest mass)
(m = the mass of particle)
(v = the speed of the particle)
(c = the speed of light)
let v/c goes to higher value,
the 1-v^2/c^2 goes less.
If v=0.1 c so( 0.1 c)^2/c^2)=0.01
[1–0.01]^1/2=[0.99]^1/2 =[99}^1/2/10=~ 0.94 M=m(1/0.95)=(100/95) m
M>m(1.005)=1.005 m.
Therefore the increase in the mass at speed (0.1 c) is about 0.005 m.
Hence, the correct answer is option (A) i.e 0.005

Answer:
The fractional increase of mass of a particle for velocity 0.1c is A. 0.005
Explanation:
Given:
velocity(v) = 0.1c
To find:
Increase in the mass =?
Formula:
Solution:
In the given formula, m is the mass of the particle, m₀ is the rest mass of the particle, v is the velocity of the particle, and c is the velocity of light.
Substituting the given values in the above-mentioned formula, we get
m = 1.005m₀
Increase in mass = m - m₀
Increase in mass = 1.005m₀ - m₀
Increase in mass = 0.005m₀
Therefore, the increase in mass of a particle at 0.1c is 0.005
