Two small spheres with mass m = 14.8 g are hung by silk threads of length L = 1.23 m from a common point. When the spheres are given equal charges, so that q1=q2=q, each thread hangs at an angle θ = 30.0o from the vertical. The system is in equilibrium. Calculate the magnitude of q

a. are

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
