The length (L) of a simple pendulum is directly proportional to the square of the time period (T). Which type of graph can best describe this relationship? A. hyperbolic B. inverse C. linear with negative slope D. linear with positive slope E. quadratic PLS HURRY I NEED THE ANSWER ASAP!!!

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
