A point charge of 5.0 x 10^-7 C moves to the right at 2.6 x 10^5
m/s in a magnetic field that is directed into the screen and
has a field strength of 1.8 x 10^-2 T.
What is the magnitude of the magnetic force acting on the
charge?

2.3 x 1011 N.

continuous conducting path for current, power supply

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
