Aproton is released from rest at the positive plate of a parallelplatecapacitor. it crosses the capacitor and reaches the negativeplate with a speed of 50,000 m/s. what will be the final speed ofan electron released from rest at the negative plate

2.1406 × m/sec

Explanation:

we know that energy is always conserved

so from the law of energy conservation

here V is the potential difference  

we know that mass of proton = 1.67× kg

we have given speed =50000m/sec

so potential difference

now mass of electron =9.11×

so for electron

so the velocity of electron will be 2.1406× m/sec

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
