Because magnet involves 2 opposite poles so therefore it would have to be C
Answer: The net charge on the sphere is -5.9nC
Explanation:
The electric field outside the conducting solid sphere is given as:
E = (kq)/r^2
Here, q is the net charge on the sphere and r is the distance from the center of the sphere.
The net charge is calculated as follows;
q = Er^2/k
E = 2.7*10^3N/C
r = 14cm = 0.14m
k = 8.99*10^9Nm^2/C^2
q = (2.7*10^3)(0.14^2)/(8.99*10^9)
q = 5.9*10^-9C
= 5.9nC
As the electric field directed radially inward, the net charge on the sphere is negative.
Hence the net charge on the sphere is -5.9nC
