Question

Consider two conducing plates A and B, between which the potential difference is 5V, plate A being at a

higher potential. A proton and an electron are released at plates A and B respectively. The two particles then

move towards the opposite plates - the proton to plate B and the electron to plate A. Which one will have

a larger velocity when they reach their respective destination plates?

A) Both will have the same velocity B) The electron will have the larger velocity

C) The proton will have the larger velocity D) None will be able to reach the destination point​

Answer 1

Answer:

Answer is B.THE ELECTRON WILL HAVE LARGER VELOCITY.

Between two conducting plate,there is the uniform electric field and therefore the same charge is applicable on both proton and electron.Since proton mass is more than that of electron it will have less acceleration and hence less speed achieved by it. So electron will reach the plate with large velocity.
