A proton (q=+5x10-19C) is injected from right to left into a field B of 0.5 T directed toward the upper side of a sheet of paper. If the velocity of the proton is of 4x106m/s, find the magnitude of the magnetic force over the proton.
F= 10 N
F=1012 N
F=1×10−12 N
F=1x10−12 T
A wire 30 cm long conducts a current of 3 A perpendicular to the direction of a magnetic field B=0.5T. Find the magnetic force in Newtons over the wire. (Write only number, First 2 decimal places, No units)
