Q. Four identical masses of mass 900 each are placed at the corners of a square whose side lengths are 15.0 .What is the magnitude of the net gravitational force on one of the masses, due to the other three?

Q. A wire loop of radius 0.30m lies so that an external magnetic field of magnitude 0.30T is perpendicular to the loop. The filed reverses its direction, and its magnitude changes to 0.20T in 1.5s. Find the magnitude of the average induced emf in the loop during this time.
