Consider a charge Q = -740 µC located at the origin. Calculate the (signed) magnitude of the electric field 6.63 m away from the charge. What angle (measured counter-clockwise) does the electric field make with the positive x-axis, at the point (x,y) = (3.8 m, 9.0 m)?
A charge of -6.4 µC is located at the origin; a charge of 8.53 µC is located at x = 0.2 m, y = 0; a third charge Q is located at x = 0.32 m, y = 0. The force on the 8.53 µC charge is 1092.3 N, directed in the positive x direction. Determine the charge Q. With this configuration of three charges, where, along the x direction, is the electric field zero? x1=? and x2=?
A charge of -5 µC is located at the origin; a charge of 6.67 µC is located at x = 0.2 m, y = 0; a third charge Q is located at x = 0.32 m, y = 0. The force on the 6.67 µC charge is 666.7 N, directed in the positive x direction. With this configuration of three charges, where, along the x direction, is the electric field zero?
A charge is located at the origin, another charge is located somewhere on the ty axis, another charge is located somewhere on the -y axis, and a fourth is located somewhere on the +x axis. The angle of the total electric force on the charge at the origin is 27 degrees counter-clockwise from the +x axis. Then, the charge at the origin changes sign and its magnitude (absolute value of its charge) increases by a factor of 2.7. All other...
