Q. The head of a rattlesnake can accelerate at 50.0 m/s^2 in striking a victim. If a car could have the same acceleration, how long would it take for it to reach a speed of 100.0 km/h from rest?
Q. A charge of -4.00 nC and a charge of -5.40 nC are separated by a distance of 70.0 cm. Find the position at which a third charge of +7.60 nC can be placed so that the net electrostatic force on it is zero.
