Show how you would make the figure for the sine and cosine function in part (b). Shows ALL the steps.

*17 In Fig. 21-28a, particles 1 and 2 have charge 20.0 uC each and are 1+ held at separation distance d = 1.50 m. (a) What is the magnitude of the electrostatic force on particle 1 due to particle 2?
