Use the formula a = |q|*v*B / m, where q is the charge, v is the velocity, B is the magnetic field, and m is the mass. This is alos equal to a = F / m.Since the velocity is not given, use the formula v = (2*KE / m)^(1/2).eport Abuse.

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, a quantity that is measured in metres per second (m/s or mâs â1) in the SI (metric) system.or example, 5 metres per second is a scalar (not a vector), whereas 5 metres per second east is a vector. If there is a change in speed, direction, or both, then the object has a changing velocity and is said to be undergoing an acceleration.
