Answer 1

Problem-1

Given is:-

radial distance  

Part-a

The electric field at the position of the electron due to the proton will be

by plugging all the values we get

which gives us

Part-b

The voltage will be

by plugging all the values we get

or

Part-c

Energy stored will be

9 х 109 х (1.бы 10-19)(-1.6 х 10-19) (0.53 10-10)

which gives us
