Problem 39E

Two large, parallel, metal plates carry opposite charges of equal magnitude. They are separated by 45.0 mm, and the potential difference between them is 360 V. (a) What is the magnitude of the electric field (assumed to be uniform) in the region between the plates? (b) What is the magnitude of the force this field exerts on a particle with charge +2.40 nC? (c) Use the results of part (b) to compute the work done by the field on the particle as it moves from the higher-potential plate to the lower. (d) Compare the result of part (c) to the change of potential energy of the same charge, computed from the electric potential.

Step-by-Step Solution:

Solution 39E Step 1 of 4: a) The magnitude of the electric field is , E = V ab= 360 V = 8000 V /m d 0.0450 m Step 2 of 4: 9 5 b)The magnitude of force is, F = q E =| |.40 × 10 C)(8000 V /m) = 1.92 × 10 N
