Question

in x-ray tube the electric field exerts a force of 3.2*10-²¹on an electron upto the distance of 0.20m what will be kinetic energy of electron if its initial energy is zero​

Answer 1

Answer:

don't know the answer sorry

Answer 2

Change in KE= work done

KE2-KE1=FS

KE2=3.2×10^-21×0.2

= 64×10^-23 J
