When two identical ions are separated by a distance of 5.9 10-10 m, the electrostatic force each exerts on the other is 6.0 10-9 N. How many electrons are missing from each ion?
A -11 mC charge experiences a force of 95 N directed north. What is the electric field magnitude and direction at the location of the charge?
The drawing shows a device that can be used to measure the speed of a bullet. The device consists of two rotating disks, separated by a distance of d = 0.650 m, and rotating with an angular speed of 60.0 rad/s. The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is θ = 0.320 rad. From these data, determine the speed of the bullet.
a 4.0- sled with ropes, as indicated in the figure . Both teenagers pull with a force of 55 at an angle of 35 relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 .

A baseball outfielder throws a 0.150-kg baseball at a speed of 38.8 m/s and an initial angle of 26.0°. What is the kinetic energy of the baseball at the highest point of its trajectory?
In the design of a supermarket, there are to be several ramps connecting different parts of the store. Customers will have to push grocery carts up the ramps and it is obviously desirable that this not be too difficult. The engineer has done a survey and found that almost no one complains if the force directed up the ramp is no more than 20 .Ignoring friction, at what maximum angle should the ramps be built, assuming a full 28 grocery cart?
The deflection plates in an oscilloscope are 10 cm by 2 cm with a gap distance of 1 mm. A 100 volt potential difference is suddenly applied to the initially uncharged plates through a 950 ohm resistor in series with the deflection plates. How long does it take for the potential difference between the deflection plates to reach 75 volts?
