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.

- Assuming that the rate of change of the price P of a certain commodity is proportional to the difference between demand D and supply S at any time t, the differential equations describing the price fluctuations with respect to time can be expressed as: dP/dt = k(D - s) where k is the proportionality constant whose value depends on the specific commodity. Solve the above differential equation by expressing supply and demand as simply linear functions of price in the form S = aP - b and D = e - fParrow_forwardFind the area of the surface obtained by rotating the circle x² + y² = r² about the line y = r.arrow_forward1) Find the equation of the tangent line to the graph y=xe at the point (1, 1).arrow_forward
