We know that electrostatic force = kq1q2/r²

And electric field= kq1/r²

So we can say field= force/charge

Now force = mass * accn

Accn = metre / time²

So dimensions of force = M¹L¹T^-2

Charge = I(current) * time

So dimensions of charge= A¹T¹

From this dimensions of field comes to be = M¹L¹T^-2/A¹T¹ =

= M¹L¹T^-3 A^-1Answer:

F=qvB and also F=qE

By above equation dimensionally.

Bv=E

Or, B=E/v

Or, 【B】= 【E】/【v】 = 【M L T^-3 A^-1】/ 【L T^-1】

=【M T^-2 A^-1】
