To find the magnitude and sign of the charge given the electric potential at a distance from it, we can follow these steps: ### Step 1: Understand the formula for electric potential The electric potential \( V \) due to a point charge \( Q \) at a distance \( R \) is given by the formula: \[ V = \frac{kQ}{R} \] where \( k \) is the electrostatic constant, approximately \( 9 \times 10^9 \, \text{N m}^2/\text{C}^2 \). ...
