If the potential due to a point charge is $5.00 \times 10^{2} \mathrm{V}$ at a distance of $15.0 \mathrm{m},$ what are the sign and magnitude of the charge?
Added by Theresa L.
Step 1
Step 1: Use the formula for potential due to a point charge: \( V = \frac{k \cdot Q}{r} \), where \( V \) is the potential, \( k \) is the Coulomb's constant, \( Q \) is the charge, and \( r \) is the distance from the charge. Show more…
