Learning Task 2
Solve the following problems. Show your solution.
1. A proton (charge +e = 1.602 x 10-19 C) moves in a straight line from
point a to point b inside a linear accelerator, a total distance d 0.50
m. The electric field is uniform along this line, with magnitude E = 1.5 x
107 V/m = 1.5 x 107 N/C in the direction from a to b. Determine a) the
force on the proton; b) the work done on it by the field; c) the potential
difference Va - Vb.
2. A charge of q = -5.3 nC is accelerated from rest through a potential
difference of 25 V. What is the change in electric potential energy of
the charge?
Electric potential energy can be defined as the capacity for doing work
