An electron and a proton, initially at rest, are pushed by the same force. Which of the two will have greater velocity? A) proton

B) electron

C) they will have different acceleration but the same velocity

D) the velocity of both the electron and the proton will be same.

The right option is choice B) electron.

Option D) the velocity of both the electron and the proton will be same is correct

Explanation:

A proton and an electron both moving with the same velocity v enter into a region of magnetic field directed perpendicular to the velocity of the particles. They will now move in circular orbits such that.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

the answer is a. at the equator
