You have an arbitrary distribution of negative charge contained within a sphere of radius RR. Describe the electric field at a distance 100R100 R from the charge distribution. 1/(100)^2 =10^-4 Now choose from one of the following optionsWhy? a The field will be in the direction normal to the charge distribution. b The field will be in the direction tangential to the charge distribution. c The field will be zero at this position. d The field will be infinite at this position.

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.)
