Question

Dimension formula of(a) electric field.....(b) magnetic field b

Answer 1

Answer:Hello Dear.

(a)We know that the formula of Electric field E is :- 

 E= F/q 

 Now changing into dimensions.

 E= MLT⁻² / I.T

 E= MLT⁻³ I⁻¹ 

Hence the dimensional formula of Electric field is MLT⁻³I⁻¹ .

(B) We know that the formula of Magnetic field B is :- 

 Magnetic field, B=  

Now changing into dimensions.

B = MLT⁻² / [IT] [LT⁻¹]

B=  MT⁻² I⁻¹

Hence the dimensional formula of Magnetic Field B is MT⁻²I⁻¹ .
