Question

At the equator, near the surface of Earth, the magnetic field is approximately 58.0 At the equator, near the surface of Earth, the magnetic field is approximately 58.0 At the equator, near the surface of Earth, the magnetic field is approximately 58.0 T northward and the electric field is about 270N/C downward in fair weather. Find the gravitational, electric, and magnetic forces on an electron with instantaneous velocity of 6.00 At the equator, near the surface of Earth, the mag 106 m/s directed to the east in this environment. gravitational N up or down electric N up ordown magnetic N up or down

Explanation / Answer

Part A)

The gravitational force is its weight

W = mg

W = (9.11 X 10-31)(9.8)

W = 8.93 X 10-30 N Downward

Part B)

For the electric field

F = qE

F = (1.6 X 10-19)(270)

F = 4.32 X 10-17 N

The direction is upward since an electron is a negative charge

Part C)

For the magnetic force...

F = qVB

F = (1.6 X 10-19)(6 X 106)(58 X 10-6)

F = 5.57 X 10-17 N

The direction, by the right hand rule, is downward
