The mass of one of the small spheres of a cavendish balance is 0.0100 kg, the mass of the nearest large sphere is 0.500 kg, and the center-to-center distance between them is 0.0500 m. find the gravitational force on each sphere due to the other.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

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.)

Explain why you think this diagram shows what happened to the carbon in the biodome.
