Answer:
Displacement is the shortest distance travelled from the initial point to the final point. After half revolution the displacement is the length of the diameter which is equal to 2r. Hence the displacement is 2r.

Answer:
9.216 x 10^-8 N
Explanation:
q1 = 1.6 x 10^-19 C
q2 = - 1.6 x 10^-19 C
r = 5 x 10^-11 m
(a) The electrostatic force is given by
F = k q1 q2 / r^2
F = ( 9 x 10^9 x 1.6 x 10^-19 x 1.6 x 10^-19) / (5 x 10^-11)^2
F = 9.216 x 10^-8 N
This force is attractive in nature, as both the charges are opposite in nature.
