Write a quantitative problem of your own involving the following variables: muscle tension, angle of muscle attachment to the bone, distance of the attachment from the joint center, and torque at the joint. provide a solution for your problem.

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
