Q. The dimensions of kinetic energy is:
KEAM
KEAM 2004
Physical World, Units and Measurements
A
$ [{{M}^{2}}{{L}^{2}}{{T}^{1}}] $
5%
B
$ [{{M}^{1}}{{L}^{2}}{{T}^{1}}] $
4%
C
$ [{{M}^{1}}{{L}^{2}}{{T}^{-2}}] $
65%
D
$ [{{M}^{1}}{{L}^{2}}{{T}^{-1}}] $
13%
E
$ [{{M}^{2}}{{L}^{2}}{{T}^{-2}}] $
13%
Solution:
$ KE=\frac{1}{2}m{{v}^{2}} $
$ \therefore $ $ [KE]=[M]{{[L{{T}^{-1}}]}^{2}}[M{{L}^{2}}{{T}^{-2}}] $
