Answer:

[M^1T^{-2}A^{-1}]

Explanation:

We are given that force on the charge e is given b y the magnitude of vector

F=Bev

We have to find the dimensions of B vector

We know that dimension of Force=[M^1LT^{-2}]

Dimension of charge=[AT]

Dimension of velocity=[LT^{-1}]

Substitute  all values then we get

B=\frac{F}{ev}

B=\frac{[MLT^{-2}]}{[AT]\cdot[LT^{-1}]}

B=[M^1T^{-2}A^{-1}]

Hence, the dimension of B=[M^1T^{-2}A^{-1}]
