Question
If the velocity of light (c), gravitational constant (G) and Planck's constant (h) are chosen as fundamental units, then the dimensions of mass in new system is
Answer: Option C
:
C
Letm∝cxGyhz
by substituting the following dimentions :
[c] = LT−1;[G] = [M−1L3T−2]and [h] = [ML2T−1]
Now comparing both sides we will get
x = 12;y=−12,z=+12
So m∝c12G−12h12
