Calculate the electric force that exists between two objects that are 5.0 x 10 m apart and carry charges of 2.5x 10°C and -3.2 x 10-6C. Is this force attractive or repulsive?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
