The surface charge density on an infinite charged plane is −1.70 x 10^−6 c/m^2 . a proton is shot straight away from the plane at 1.90 x 10^6 m/s . how far does the proton travel before reaching its turning point?

Acceleration of proton will be

Explanation:

We have given surface charge density of an infinite charged plate

Electric field due to infinite sheet charge is given by

Charge in proton is given by

So force on proton

Mass of proton

According to newtons second law force F = mass × acceleration

So
