The force that a charge experiences when placed at a point is given by:
We also need Newton's second law of motion here, which is expressed as:
Comparing the two equations:
A uniform electric field exists in the region between two oppositely charged plane parallel plates. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate, 1.20 cm distant from the first, in a time interval of 3.80×10−6 s
Find the magnitude of the electric field.
Find the speed of the proton when it strikes the negatively charged plate.
