Question
The diagram below shows some of the lines of electric force around a positive point charge.The strength of the electric field is(A) greatest at point $A$(B) greatest at point $B$(C) greatest at point $C$(D) equal at points $A, B$, and $C$
Step 1
Step 1: The electric field strength or intensity is given by the formula $E = \frac{KQ}{R^2}$, where $E$ is the electric field strength, $K$ is Coulomb's constant, $Q$ is the charge of the source, and $R$ is the distance from the source. Show more…
