A proton is moving at 2.20 km/s in the x direction. in a vector magnetic field B = 3.0x10^-5 T I - 2.1x10^-5 T j - 6.7x10^-5 T K.

a. 0.214 N
b. 2.36 x 10^-20 N
c. 7.40 x 10^-21 N
d. 2.47 x 10 ^-20 N

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them
