Question

A proton moves through a region of space where there is a magnetic field B⃗ =(0.65i+0.37j)T and an electric field E⃗ =(3.1i−4.4j)×103V/m. At a given instant, the proton's velocity is v⃗ =(5.4i+2.9j−5.1k)×103m/s. Find Fx, Fy, Fz in N

Answer #1

The total force on the proton is

** F**
=

= *e*{(3.1**i** -4.4**j**) x
10^{3}V/m + [(5.4**i** + 2.9**j**
- 5.1**k)** x 10^{3}m/s x
(00.65**i** + 0.37**j)T**]}

= (1.60 x 10^{-19}C)[(3.0**i** -
4.2**j**) + (1.887i -3.315j 0.113k)] x
10^{3}V/m

= (7.82**i** -
12.024**j** - 0.1808**k**)] x
10^{-16}N.
