A charge of -2.95 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass, which has a radius of 0.097 m. The charges on the circle are -3.85 µC at the position due north and +5.20 µC at the position due east. What are the magnitude and direction of the net electrostatic force acting on the charge at the center? Specify the direction relative to due east.
Magnitude ____
Direction ______
A diver 40 m deep in 10 degree Celcius fresh water exhales a 0.50-cm-diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 20 degrees Celcius? Assume that the air bubble is always in..
When he reaches equator, the sphere is rotating at how many rpm. A car takes 9 s to go from v = 0 to v = 55 m/s at about constant acceleration.
Establish the initial volume of the gas . What is the magnitude of normal force that each brake pad applies to the rim.
A duck has a mass of 2.6 kg. As the duck paddles, a force of 0.11 N acts on it in a direction due east. In addition, the current of the water exerts the force of 0.12 N in a direction of 44° south of east. When these forces begin to act, the velocity..
Suppose that a structure of arbitrary complexity has a number of forces applied to it (at various points) and yet is in static equilibrium. The principle of virtual work allows one to write an equation that relates the applied forces.
