Two iron spheres are suspended from strings and
separated by a distance of 9.0 meters. The
charge on one sphere is 7.0*10^-8 Cand the other -3.0
*10^-5 C. What is the electric force on the spheres?
A. A repulsive force of 4.6*10^-4N
B. An attractive force of 2.3*10^-4 N
C. An attractive force of 4.6*10^-4 N
D. A repulsive force of 2.3*10^-4 N

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
