Question

What is the magnetic force on a proton that is moving at 3.8 answer test box choice a 2.0 107 m/s up through a magnetic field that is 0.72 T and pointing toward you? The charge on a proton is 1.6 answer test box choice a 2.0 10-19 C. Use F = qv answer test box choice a 2.0 B sintheta. A. 4.4 answer test box choice a 2.0 10-12 N left B. 6.1 answer test box choice a 2.0 10-12 N left C. 4.4 answer test box choice a 2.0 10-12 N right D. 6.1 answer test box choice a 2.0 10-12 N right

Answer 1

4.4 x 10^-12

Step-by-step explanation:

:D

Answer 2

Step-by-step explanation:

Given:

q = 1.6·10⁻¹⁹ С - proton charge

V = 3.8·10⁷ m/s - proton speed

B = 0.72 T - magnetic field induction

_____________

F - ?

Lorentz force:

F = q·B·V

F = 1.6·10⁻¹⁹·0.72·3.8·10⁷ ≈ 4.4·10⁻¹² N

Force is directed to the right.
