A cloud has a potential difference relative to a car of 7.66 x 108 volts. During a lightning storm, a charge of 19.3 coulombs travels through this potential difference. If the energy released could somehow be harnessed and converted into kinetic energy, how fast could Mr. Baud's 2020 Kia Sorento move? His car has a mass of 1850 kilograms and starts from rest. Include units in your answer.

On planet Tehar, the free-fall acceleration is the same as that on Earth, but there is also a strong downward electric field that is uniform close to the planet's surface. A 1.98-kg ball having a charge of 5.22 ?C is thrown upward at a speed of 20.1 m/s. It hits the ground after an interval of 4.10 s. What is the potential difference between the starting point and the top point of the trajectory? (Use 9.8 m/s2 for the acceleration due to gravity.)

You are working in a laboratory, using very sensitive measurement equipment. Your supervisor has explained that the equipment is also very sensitive to electrical discharge from human operators. Specification tables for the equipment indicate that an electrical discharge providing even a very small amount of energy of 250 μJ is enough to damage the equipment. Your supervisor wants to install an apparatus that will be used to remove the electrical charge from individuals’ bodies before they touch the equipment. To do this, she asks you to estimate (a) the capacitance of the human body and determine (b) the charge on the body and (c) the electric potential of the body, relative to a point infinitely far away, corresponding to the energy transfer that will damage the equipment.

A particle of mass 3 × 10−5kg and charge1 µC moves downward from point A to pointB a distance of 3 m in the earth’s gravitational field. The kinetic energy of the particledecreases by 3.6 mJ during this movement.What is the potential difference VB − VA?The acceleration of gravity is 9.8 m/s2.Answer in units of kV.

A metallic sphere with a radius of 0.11 m has been charged to +39 V. A particle with mass 2.5 x 10 kg and charge -4.4 µC is released from rest at a position that is 0.79 m away from the center of the charged metal sphere. What is the mechanical energy of this system? What will the electric potential energy of this system be when the particle reaches the surface of the sphere? What will the kinetic energy of the particle be when it reaches the surface of the sphere? What will be the speed of this particle when it reaches the surface of the sphere?
