question 1:

question 1: A particle of mass 6.5×106 kg and charge 37 C is moving at a speed of 22 m/s perpendicularly to a uniform 7.8-T magnetic field. What is the radius of the particle’s circular path? please give me the answer in m.

question 2: A 15.0 ampere current flows through a 6.00 m section of wire, perpendicular to a 0.250 T magnetic field. What is the magnitude of the force exerted by the field on the wire section? please give me the answer in N.

Explanation / Answer

1) here magnetic foerce = centri petal force

qvB = mv^2/r

r = mv/qB

r = 6.5*10^-6*22/37*10^-6*7.8

r = 0.495 m

2) magnetic force in a wire f = Bil sintheta

here theta = 90

f = Bil

f = 0.25*15*6 = 22.5 N
