Q. Two negative point charges are separated by 16 and feel a mutual repulsive force of 1.55. The charge of one is three times that of other.
1. Two negative point charges are separated by 16.0 and feel a mutual repulsive force of 1.55. The charge of one is three times that of other.
2. What would be the force if the total charge were instead evenly distributed on both point charges?
A wrench 0.3 meters long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of langle 0, 1, 2rangle at the end of the wrench. Find out the magnitude of the force in newtons needed to give 100 newton..
