Question 21 POST_UTME_BSU • 2022 • PHYSICS • objective

A uniform solid sphere of radius $R$ and mass $M$ is placed at the origin of a coordinate system. A point charge $q$ is placed at a dis\tance $r$ from the origin, where $r > R$. What is the magnitude of the electric field at the point charge $q$?

Answer Options

Correct Answer A. \( \frac{kq}{r^2} \left\( 1 - \frac{3R^2}{2r^2} + \frac{R^4}{2r^4} \right \)
B. \( \frac{kq}{r^2} \left\( 1 + \frac{3R^2}{2r^2} + \frac{R^4}{2r^4} \right \)
C. \( \frac{kq}{r^2} \left\( 1 - \frac{R^2}{2r^2} + \frac{R^4}{2r^4} \right \)
D. \( \frac{kq}{r^2} \left\( 1 + \frac{R^2}{2r^2} + \frac{R^4}{2r^4} \right \)
Correct Answer
A
Correct Option:
\( \frac{kq}{r^2} \left\( 1 - \frac{3R^2}{2r^2} + \frac{R^4}{2r^4} \right \)
