At time t=0 a proton is a distance of 0.360 m from a very large insulating sheet of charge and is moving parallel to the sheet with speed 960 m/s . The sheet has uniform surface charge density 2.34.×10−9C/m2 . What is the speed of the proton at 5.40

Explanation:

Formula for the electric field due to the infinite sheet of charge is as follows.

               E =

where,   = surface charge density

Now, formula for electric force acting on the proton is as follows.

             F = eE

where,    e = charge of the proton

According to the Newton's second law of motion, the net force acting on the proton is as follows.

                       F = ma

                 a =

                    =

                    =

According to the kinematic equation, speed of the proton in perpendicular direction is as follows.

                     =

                     =

                     = 683.974 m/s

Hence, total speed of the proton is as follows.

                v' =

                    =

                    =

                    = 1178.73 m/s

Therefore, we can conclude that speed of the proton is 1178.73 m/s.
