A conducting sphere of radius 20.0 cm carries an excess charge of +15.0 µC,and no other charges are present.(k = 1/4πε₀ = The potential (relative to infinity)due to this sphere at a point 12.0 cm from its center is closest to

Question

Quizplus · Accepted Answer

We can use the formula for the potential due to a charged sphere:
V = k*q/r

where V is the potential at a distance r from the center of the sphere, q is the charge on the sphere, and k is the Coulomb constant.

Substituting the given values, we get:
V = (1/4πε₀)(15.0×10⁻⁶ C)/(0.12 m) = 673.8 kV

Thus, the closest answer option is B) 674 kV.
