Question

3)The Earth magnetic field is about 5x10s Tesla and point to north, a negative charge Of 50 nc moves at the speed of 10 m/s, find the value charge move to 60 northwest at speed of 10 m/s, b) the charge move to north at speed of 10 m/s, c) the charge move to east at speed of 10 m/s, d) the charge move to south at speed of 1 m/s, e) the charge move to w in each case the direction of the m or out of the paper by right hand rule) s and directions for the following conditions: a) the est at speed of 10 m/s. (if the force is not 0, you need to indicate agnetic force on the charge is either going into to the paper

Explanation / Answer

Let North be positive Y and East be positive X axis

B = 5 x 10^5 j

q = 50nc

V = 10m/s

Force = q V x B

a.> v = 10 ( cos 60 i + sin 60 j)

F = .125 out of paper

b.> v = 10 ( cos 90 i + sin 90 j)

F = 0

c.> v = 10 ( cos 0 i + sin 0 j)

F = ,25 out of paper

d.> v = 10 ( cos -90 i + sin -90 j)

F = 0

e.> v = 10 ( cos 180 i + sin 180 j)

F = -.25 inside the paper
