The voltage is mapped out everywhere in in a 2D-space for a certain distribution of charge. The voltage data is presented in the table to the right and each value is in volts.
(a) Map out these voltage values and sketch a set of equipotential surfaces for V = -400V, -100V, 200V, 500V, 800V and 1100V.
(b) Sketch the electric vector field.
(c) What is an equation for the electric potential as a function of x and y?
(d) What is the electric field as a function of x and y?
two charged spheres are 5.27cm apart. they are moved and the force on each of them is found to have been tripled how

To get to a concert in time, a harpsichordist has to drive 120 miles in 2.08 hours. What is his average velocity for the entire trip
A 95 kg man standing on a surface of negligible friction shoves a 75 g stone lying at his feet, giving it a velocity of 4.0 m/s. What velocity does the man obtain accordingly.
A catapult on a cliff launches a large round rock towards a ship on the ocean below. Calculate the speed at which the rock is launched
Two boxes of massm1 = 15 kg and mass m2 = 22 kg are linked by a spring with spring constant k =62 N/m. The mass of the spring is negligible. A horizontal force of F = 180 Nis applied to mass m1, which is to the left of massm2, causing both boxes to m..
