Pleaseeee help me..
What is the electric force between a +2 µC point charge and a –2 µC point charge if they are separated by a distance of 5.0 cm? (µC = 1.0 × 10–6 C)

Best ResponseYou've already chosen the best response.3Coulomb's Law: \[F=K{q_1q_2\over d^2}\] \[K = const.\\ q_1 = 2\times10^{6}C\\ q_2= 2\times10^{6}C\\ d=5{\rm cm}\times {1{\rm m}\over 100{\rm cm}}=0.05{\rm m} \]

Best ResponseYou've already chosen the best response.3we plug em in the equation for the force. \[ F=8.99\times10^{9}\times \frac{2\times10^{6}\times2\times10^{6}}{(0.05)^2} \]

Best ResponseYou've already chosen the best response.3the negative sign can be neglected since we are only looking for the magnitude (i.e., the amount) of force. since the two charges are oppositely charged, the above force will be a force of attraction. this is the information we get from the charges
