Electromagnetic Field Theory - Engineering

Q1:

The force in a magnetic field is given by F = qvB

A F and q are perpendicular and v and B are perpendicular

B F and q only are perpendicular to each other

C F and v, F and B are mutually perpendicular to each other and v and B at any angle between them

D All the four components are perpendicular to each other

ANS:A - F and q are perpendicular and v and B are perpendicular

Q is scalar and has no direction. So option c is the correct answer.
