Given a charge q, current I and permeability of vacuum _o^*. Which of the following quantity has the dimension of momentum?

Question

Accepted Answer

Correct answer: D. (d) Q=AT I=A _0= MLT^-2A^-2 P=Q^x _0^yI^z= (AT^x ( MLT^-2A^-2 )^y [A ]^z ) MLT^-1=M^yL^yT^x-2yA^-2y+z+xNow; y=1 x-2y=-1 -2y+z=0 ∴x=y=z=1
