From the picture: a. determine the electric potential at point P. b. determine the work done to place the charge 3.00 uC at point P. What is the total electric potential energy of the system?
Directions: Write “Potential" if the statement is true, if it is false write "Electric" and change/supply the underlined word/phrase with a correct answer. 1. A positive charge accelerates from a region of higher electric potential toward a region of lower electric potential. 2. Volt is used as the unit for electric potential to honor the scientist who discovers it. The name of this scientist is Charles Voltaire. 3. Electric potential energy and electric potential have the same unit which is expressed in volts. 4. Electric force is associated with potential energy and is a conservative force. 5. The potential difference between two points is measured in volts and is often referred to as a voltage.

44. A metal ramp 6.00 m long is tilted 10.0° and is used to load and unload a moving van. Suppose a 20.0 kg box is pushed up the ramp and it slides with a friction coefficient of 0.30. The ramp can be viewed as a "machine" where the useful output is the potential energy gain of the box and the input is the physical work done by the person doing the pushing. (a) Determine the efficiency of the ramp. (b) Determine the ratio of the force needed to lift the box without the ramp to the force needed to push it along the ramp (this is called the mechanical advantage).
