Two point charges of 60.0 C and -12.0 C are separated by a distance of 20.0 cm. A 7.00 C charge is placed midway between these two charges. What is the electric force acting on this charge because of the other two charges

Explanation:

Distance between q1 and q2,d=20 cm

1m =100 cm

Electric force on charge q3 due to charge q1

(away from q1)

Electric force on charge q3 due to charge q2

(attract toward q2)

Net force=

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
