Electrostatic force The magnitude of the electrostatic force between two point charges Q and q of the same sign is given by
- a. Find the instantaneous rate of change of the force with respect to the distance between the charges.
- b. For two identical charges with Q = q = 1 C, what is the instantaneous rate of change of the force at a separation of x = 0.001 m?
- c. Does the magnitude of the instantaneous rate of change of the force increase or decrease with the separation? Explain.

- Frictional Force The frictional force F between the tires and the road required to keep a car on a curved section of a highway is directly proportional to the square of the speed s of the car. If the speed of the car is doubled, the force will change by what factor?arrow_forwardHookes Law Hookes Law states that the force needed to keep a spring stretched x units beyond its natural length is directly proportional to x. Here the constant of proportionality is called the spring constant. a Write Hookes Law as an equation. b If a spring has a natural length of 5 cm and a force of 30 N is required to maintain the spring stretched to a length of 9 cm, find the spring constant. c What force is needed to keep the spring stretched to a length of 11 cm?arrow_forward
