A uniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance 5.4 cm. A proton is released from rest at the surface of the positively charged plate. The value of the constant electric field between the plates is 166.8 N/C.

Use:

Mass of a proton= 1.67 × 10-27 kilograms

Charge of a proton = 1.60 × 10-19 C

k = 9 x 109 Nm2 / C2

ε0 = 8.85×10−12 F⋅m−1
