a student measure the mass of five steel hex nuts to be 96.2g the hex nuts displace 13 ml water. calculate the density of the steel in the hex nuts!

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.)
