Hank is pulling his brother, Benji, on a sled with constant velocity across horizontal ground. The rope attached to the sled makes a 57° angle with the ground. If Hank pulls the rope with 500 N of force, and the combined mass of Benji and the sled is 42 kg, how much normal (support) force does the ground exert on the sled?

Acharge q experiences no net force at a particular point in space. which of the following situations described below must always be true? -there are no other charges nearby. -if there are other charges nearby, they must all have the same sign as q. -if there are other charges nearby, they must all have the opposite sign of q. -if there are other charges nearby, the total positive charge must equal the total negative charge. -none of the above
