Two forces are acting on an object. which of the following statements is correct, if the object experiences translational and rotational equilibrium? oa the object is in equilibrium if the forces are equal in magnitude and opposite in direction o b. the object is in equilibrium if the forces act at the same point on the object. o c. the object is in equilibrium if the net force and the net torque on the object are zero. od. the object is in equilibrium if the net torque on the object is zero. oe. an object will never be in equilibrium with two or more forces acting on it.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
