In a repair shop a truck engine that has mass 409 kg is held in place by four light cables (Fig. P5.63). Cable A is horizontal, cables B and D are vertical, and cable C makes an angle of 37.1o with a vertical wall. If the tension in cable A is 722 N, what are the tensions in cables B and C?
If the charge is greater than zero (positive) then E field force goes out of reference point and if below zero (negative) then the E field force goes in to reference point Charge magnitude unless specified is 1.6E19 C E = kq/r = mg/q F = Eq E field force only requires one charge to be present Positive charge field points to negative charge At point S, the distance is shorter to the electron and thus the will be affected more by this charge than the proton (pointing in to electron), while at point R it is closer to the electron so it will feel more of an affect from this charge. The proton field is also going toward the electron so either way the force field felt by point R will be to the left. Quiz review/explanations 1. positive charge goes to negative charge 2. field
