The charges -q3 and +q4 exert an attractive force of 30 N on each other. If -q3 is replaced with a charge of -2q3, +q4 is replaced with a charge of +1/4q4, and the separation distance is decreased to 1/2d, what is the new electrostatic force?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

The heliocentric and the geocentric models of the solar system included these central principles
