Review Conceptual Example 7 as background for this problem. A positive
charge +91 is located to the left of a negative charge -92. On a line passing
though the two charges, there are two places where the total potential is zero.
The first place is between the charges and is 4.16 cm to the left of the negative
charge. The second place is 7.57 cm to the right of the negative charge. (a) What
is the distance between the charges? (b) Find 91/92, the ratio of the magnitudes
of the charges.

If it experiences an angular acceleration of 6.25rad/s², calculate the mass of the plate. Question 17 A light string is wrapped around a solid cylinder, and a block of mass m = 100g hangs from the free end of the string, as shown Figure A2.17. When released, the block falls a distance of 1.0m in 2.0s. a. Draw free-body (or force) diagrams for the block and the cylinder. b. Calculate the tension in the string. c.

The box then slides down a ramp that makes an angle of 36° with the horizontal and has a coefficient of kinetic friction equal to 0.43. After reaching the end of the ramp, the box continues to slide horizontally on the smooth floor.
