Eletric field

Electricity and Magnetism Level 4

A uniform electric field of 150 N/C downward exists near the surface of the Earth. Suppose an electron is “launched” from the end of a TV picture tube with a horizontal speed \(2.0 \times 10^7\) m/s and travels a horizontal distance of 20.0 cm before impacting the screen. Determine the acceleration of the electron due to the earth’s field.
