Solution


Q.

The dimensions [MLT-2A-2] belong to the:                          [2022]
1 magnetic flux  
2 self inductance  
3 magnetic permeability  
4 electric permittivity  

Ans.

(3)

Dimensions of magnetic flux =[ML2T-2A-1]

Dimensions of self inductance =[ML2T-2A-2]

Dimensions of magnetic permeability =[MLT-2A-2]

Dimensions of electrical permittivity =[M-1L-3T4A2]

So, the correct option is (3).
