Two identical conducting spheres, having charges of opposite sign, attract each other with a force of 0.108 N when separated by 50.0 cm. The spheres are suddenly connected by a thin conducting wire, which is then removed, and thereafter the spheres repel each other with a force of 0.036 N. What were the initial charges on the spheres?
for F=0.108N
F = (kQ^2) / r^2
Q^2 = ((0.108)(0.5)) /(8.99x10^9)
Q^2 = 6 x 10^-12
Q1q2 = 6 x 10^-12
for F = 0.036N
F = (kQ^2) / r^2
Q^2 = ((0.036)(0.5)) /(8.99x10^9)
Q^2 = 2 x10^-12
Q1q2 = 2 x10^-12
for F=0.108N
F = (kQ^2) / r^2
Q^2 = ((0.108)(0.5)) /(8.99x10^9)
Q^2 = 6 x 10^-12
Q1q2 = 6 x 10^-12
for F = 0.036N
F = (kQ^2) / r^2
Q^2 = ((0.036)(0.5)) /(8.99x10^9)
Q^2 = 2 x10^-12
Q1q2 = 2 x10^-12
