19)Calculate the force between a negative charge of 0.0068 coulombs and a positive charge of 0.00023 coulombs that are separated by 1.94
meters. Is the force attractive or repulsive? *
7,300 N of attractive force
O 7,300 N of repulsive force
3,700 N of attractive force
O 3,700 N of repulsive force

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
