Question

find the dimension of magnetic field B .. Given equation is F =qvB

Answer 1

F=qvB

Force = MLT^-2

CHARGE = AT

VELOCITY = LT^-1

MAGNETIC FIELD = FORCE/CHARGE×VELOCITY

MLT^-2/AT×LT^-1

MA^-1T^-2

Answer 2

Answer:

Magnetic field, (B)

F = qVB (given and wkt)

B = F/qV ----- (1)

F = MLT^(-2)

q = AT

V = LT^(-2)

Putting all in (1)

B = MLT^(-2)/ATLT^(-2)

[B] = [MT^(-2)A^(-1)]
