Answer:
a) 4.6*10^{-5} J
b) 6133.33 J/C
c) 94358.9 C
Explanation:
(a) We have that the change in the kinetic energy equals the net work over the charge. Hence we have
where Ek is the kinetic energy, W is the work of the external force and WE is the work done by the electric field. By replacing we obtain:
(b) The potential difference is computed by using:
(c) With the work done by the electric force we can calculate the Electric field. By using the following formula we obtain:
where we have used d=6.5cm=6.5*10^-9m and q=7.5nC=7.5*10^-9C
hope this helps!!
