Answer:
A. F=6.65*10^{-10}N
B. south - north
Explanation:
A) We use the Lorentz force
F = qv X B
|F| = qvB
to calculate the magnitude of the force we need the speed of the of the ball.
and by replacing in the formula for the magnitude of the force we have (taking into account the excess of electrons)
B)
b. south - north (by the rigth hand rule)
I hope this is usefull for you

kinetic energy or potential energy
sorry idek i learned this like 2 years ago
