How much work is done moving a charge along an equipotential surface (line)? Explain.
(c) Sketch an equipotential surface at a distance r from a point charge q, and state the magnitude of the work done in moving a small test charge along that surface. The membrane that surrounds a certain type of living cell has a surface area of 4.1 x 10¯9 m 2 and a thickness of 1.5 x 10¯8 m. Assume that the sides of the membrane behave like a pair of equipotential surfaces, with a material of dielectric constant 5.2...
How much work does the electric field do in moving a -8.0 μC charge from ground to a point whose potential is +70 V higher?
How much work is done by the electric force when a 0.50-C charge is moved from the point (2.0 cm, 1.0 cm) to the point (6.0 cm, 6.0 cm)? Express your answer to two significant figures and include appropriate units. KHW02 Problem 20.49 < 6of9 Review Part A A given system hes the equipotential surfaces shown in (Figure 1). What is the electric potential at the point (2.0 cm 1.0 cm? Express your answer to three significant figures and include...
A charge Q1=-28.9 μC is held stationary at the origin. How much energy is required to bring another charge q2=-96.6 μC from "infinity" (that is from a very very large distance from each other) to the location (2.5 cm,1.0 cm)? The answer should have correct sign and be in appropriate units.
What is the distance between a -2.00 μC charge and a -3.00 μC charge if their potential energy is 0.491 J? To solve this question you want to think at where the charge q can be for example the -2.00 μC and the other charge -3.00 μC becomes the source of the voltage V. The initial distance is very far away, and the final distance is "r" that you want to find. ( Do not forget the voltage V for a point...
6. How much work is done if a particle with +12.0 C on it moves 10 cm along an equipotential line? Explain your answer.
A +40 μC point charge is placed 54 cm from an identical +40 μC charge. How much work would be required for an external force to move a +0.40 μC test charge from a point midway between them to a point 11 cm closer to either of the charges?
A large metal plate has a surface charge density of 0.175 μC / m2. The space between the equipotential lines of 100 V in the center is: a. 1.5 cm b. 2.5 cm c.10mm d. 7.5 mm The work necessary to move a load of +2.5 mC from an equipotential surface of 10 V to another equipotential surface of 50 V is: a. 0.50J b. 0.10 J c. 10 mJ d. 1.0 J
A point charge with charge q1 = 3.10 μC is held stationary at the origin. A second point charge with charge q2 = -4.50 μC moves from the point ( 0.120 m , 0) to the point ( 0.270 m , 0.250 m ). How much work W is done by the electric force on the moving point charge? Express your answer in joules. Use k = 8.99×109 N⋅m2/C2 for Coulomb's constant: k=14πϵ0.
