WAEC - Physics (1997 - No. 42)
A charge of 1 x \(10^{-5}\)C experiences a force of 40N at a certain point in space. What is the magnitude of the electric field intensity at the point in Newton and couloumb
8 x \(10^{6}\)
4 x \(10^{6}\)
3 x \(10^{-4}\)
2 x \(10^{-4}\)
5 x \(10^{-7}\)
Explanation
\(E= \frac{F}{O}= \frac{40}{1\times10^{-5}}=4 \times10^{6}\)
