The magnitude of the electrostatic force between two point charges Q and q of the same sign is given by F(x)=x2kQq, where x is the distance between the charges and k=9×109 N⋅m2/C2 is a physical constant (C stands for coulomb, the unit of charge; N stands for newton, the unit of force). Use this information to answer parts (a) through (c) below. A. F′(x)=−x31.8×10yQq N/m B. F′(x)=−x32QqN/m F′(x)=−x31.8×1010QqN/m D. F′(x)=−x21.8×1010QqN/m b. For two identical charges with Q=q=1C, what is the instantaneous rate of change of the force at a separation of x=0.003 m ?
