A negative charge of q=-1.2x10^-17 and m= 7.8 x 10^-26 kg enters a magnetic fiel

Question

A negative charge of q=-1.2x10^-17 and m= 7.8 x 10^-26 kg enters a magnetic field B=1.1 T with initial velocity v= 95 m/s, as shown in the figure. The magnetic field points into the screen.

All parts would be appreciated and rated of course.

Explanation / Answer

the magnetic force would be in the downward direction.

by the left hand rule :

if we place our thumb, index and middle perpendicular to each other. And index finger in the direction of magnetic field, middle finger in the opposite direction of the negative charge then the thumb will be in the direction of the force.
