Q1. Two point charges 2.40 nC and 6.50 nC are 0.100 m apart. Point is midway between them; point is 8.00×10-2 m from and 6.00×10-2 m from. Take the electric potential to be zero at infinity. Find work completed by the electric field on a charge of 2.5 that travels from point to point.

Q2. A chair of weight 135 lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of = 38 directed at an angle of 42 below the horizontal and the chair slides along the floor.
