Explanation / Answer

when a charge moves in a magnetic field, the field exerts a force given by Fb = q*v*B*sintheta

v = spees of the charge

q = charge

B = magnetic field

theta = angle between the v and B

for theta = 90

F1 = q*v1*B

for theta = 24

F2 = q*v2*B*sin24

F2 / F1 = (v2/v1)*sin24

F2 = F1*v2*sin24/v1

F2 = (2.3*10^-4*6.3*sin24)/28

F2 = 2.1*10^-4 N <<<---------------answer
