Class 11 NEET Physics Physical World, Units and Measurements

Dimensions of energy E=[ML2T−2]
Dimensions of volume v=[L3]
Dimensions of force F=[MLT−2]
Dimensions of area A=[L2]
Dimensions of voltage V=[ML2T−3A−1]
Dimensions of charge q=[AT]
Dimensions of angular momentum L=[ML2T−1]
∴ Dimensions of

E

v

=[ML2T−2][L3] =[ML−1T−2]
Dimensions of

F

A

=

[MLT−2]

[L2]

=[ML−1T−2]
Dimensions of

Vq

v

=

[ML2T−3A−1][AT]

[L3]

=[ML−1T−2]
Dimensions of angular momentum is [ML2T−1] while other three has dimensions [ML−1T−2]
