Blog 10 (Mar 25) - General Physics-AB (MERGED) 2. A particle with a charge of 14 uC experiences a force of 2.2 x 10-4 N when it moves at right angles to a magnetic field with a speed of 27 m/s. (a) How large is the magnetic field? (b) What force does this particle experience when it moves with a speed of 6.3 m/s at an angle of 25° relative to the magnetic field?

Solution

a)

Magnetic Force on a charge,

F = qvB

So, 2.2*10^-4 = 14*10^-6*27*B

So, B = 0.582 T <---------answer

b)

F = qvB*sinQ

= 14*10^-6*6.3*0.582*sin(25 deg)

= 2.2*10^-5 N <-------answer
