The Electrostatic Force ( F ) Between Two Plates of a Charged

Multiple Choice

The electrostatic force ( F ) between two plates of a charged capacitor is directly proportional to the product of the charges ( $q_ 1$ and $q_2$ ) on each plate and inversely proportional to the square of the distance ( d ) between the plates.

A) $F = \frac { q _ { 1 } } { d q _ { 2 } }$
B) $F = \frac { d } { q 1 q 2 }$
C) $F = \frac { q 1 q 2 } { d }$
D) $F = \frac { q 1 q 2 } { d ^ { 2 } }$
