The bent rod is supported at a, b, and c by smooth journal bearings. the rod is subjected to the force f = 980 n . the bearings are in proper alignment and exert only force reactions on the rod. determine the components of reaction at the bearing a using scalar notation.

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
