15 10 Solutionq charge 16 x 1019 C v velocity 0045 x 3 x

Solution

q = charge = 1.6 x 10^-19 C

v = velocity = 0.045 x 3 x 10^8 m/s = 0.135 x 10^8 m/s

B = Magnetic field = 0.0120 T

m = mass = 9.1 x 10^-31 kg

a = acceleration

a)

F = qvB

F = 1.6 x 10^-19 C x 0.135 x 10^8 x 0.0120

F = 2.592 x 10^-14 N

F= 25.92 fN

Thus, the magnetic force is 25.92 fN

b)

F = m*a

2.592 x 10^-14 = 9.1 x -31 kg x a

a = 2.848 x 10^16 m/s^2

a = 28.48 x 10^15 m/s^2

a = 28.48 pm/s^2

The acceleration is 28.48 pm/s^2
