Question

The strength of a/an _____ is equal to the force on a positive test charge divided by the strength of the test charge.1) electric field2) electric field line3) capacitor4) electric potential difference

Answer 1

The electric field in terms of the force and charge is,

$E=\frac{F}{q}$

where F is the force acting on the test charge, q is the strength of the test charge, E is the strength of electric field,

Thus, the electric field strength is equal to the force on a positive test charge divided by strength of test charge.

Hence, 1st option (electric field) is the correct answer.
