A uniform electric field exists in the region between two, Ask an Expert

Academics

A uniform electric field exists in the region between two oppositely charged parallel plates 1.58cm apart. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval 1.53A x 110^-6s.

a) Find the magnitude of the electric field.

Use 1.60A x 110^-19C for the magnitude of the charge on an electron and 1.67A x 110^-27kg for the mass of a proton

b) Find the speed of the proton at the moment it strikes the negatively charged plate.
