4. Three students attempt to move a stationary mass of 26.0kg (in the X-Y plane). One student pulls with a force of 85N (N25E), another pushes with a force of 60N [N] and the other student exerts a force of 8ON [N25W]. An
additional force of 180N [S] impedes the motion of the mass. If the mass is moving fortifor 2.0 seconds,
determine the displacement of the mass. /3

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
