Question

A positively charged object will:A.have no effect on a negative charge.B.exert a pulling force on another positively charged object.C.attract a negatively charged object.D.have no effect on another positive charge.

Answer 1

When a positively charge object is at a distance of a negatively charged object then an attractive force between them is exerted. The magnitude of that force is give by:

`F=k(q_1q_2)/(r^2)`

Where:

`\begin{gathered} F=\text{ force} \\ k=\text{ Coulomb's constant} \\ q_1,q_2=\text{ charges} \\ r=\text{ distance} \end{gathered}`

therefore, the right answer is C.
