A proton moving at 7. 0 × 10^4 m/s horizontally enters a region where a magnetic field of 0. 10 t is present, directed vertically downward. What magnitude force acts on the proton due to this field?

Sagot :

A proton moving at 7. 0 × 10^4 m/s horizontally enters a region where a magnetic field of 0. 10 t is present, directed vertically downward. The magnitude force acts on the proton due to this field will be 1.12 * [tex]10^{-23}[/tex] N

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.

Force in a magnetic field = q. ( v * B )

where

q = charge of particle = 1.6 * [tex]10^{-27}[/tex] C

v = velocity of particle = 7. 0 × [tex]10^{4}[/tex] m/s

B =  0. 10 T

Force =  1.6 * [tex]10^{-27}[/tex]  * 7. 0 × [tex]10^{4}[/tex]  *  0. 10

          = 1.12 * [tex]10^{-23}[/tex] N
