A +15μC point charge is placed 10cm from a +7μC point charge.
1. Find the force experienced by the +15μC charge.
2. The force experienced by the +7µC charge. 3. What is the Net force on the +15 µC charge? 4. What is the electric field strength located at -10cm from the +7µC charge? 5. Draw the direction of the electric field line at the -5cm mark from the +7μC charge.​
