Bartolo is trying to move his bed by pushing north with a force of 320 N. His little brother and sister are trying to stop him by pushing south with 190 N and 170 N respectively. Calculate the net force acting on the bed.

Apositive point charge q is fixed on a very large horizontal frictionless tabletop. a second positive point charge q is released from rest near the stationary charge and is free to move. which statement best describes the motion of q after it is released? assume q stays on the table

Ireally need this answer sombody fast fast
