7. A negative 6 mC charge enters a region of 45 I magnetic field that is directed up. If the charge is moving toward the south with a speed of 400 m/s, determine the magnitude and
direction of the force.

i would say the answer is food.

hope this !

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

something from nucleus has changed, but charge must be same for cons of charge
