Homework Help: Physics

Posted by Phil on Thursday, January 17, 2013 at 5:43pm.

Two spheres of charge q1 and q2 that are equal in magnitude (i.e. |q1| = |q2|) are attached by a spring with a constant k = 1440kg/s2 and a rest length of x0 = 83.0cm. We take negative values of x for compression and positive x values for expansion. Knowing that q1 is positive and x = 4.40cm, what are the values of (a) q1 and (b) q2? If we know that q1 is negative and measure x = -3.50cm, then what are the values of (c) q1 and (d) q2? (hint for parts (c) and (d): take the magnitude of x under the square root sign and look at positive or negative roots for charges)
