A toy gun sitting on a table when the 0.200 kg foam bullet shoots out a 15.0 m/s. What is the velocity of the gun if it has a mass of 1.35 kg

1.94m/s

Explanation:

The best conclusion based on the description is: The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Explanation:

As we know, that the electric force that has been exerted on a charge by an electric field is given as:        

                                         F =q×E

Where,

         F = Force

         q = Charge

         E = Electric field

We, can see a negative charge, with q having a negative sign, hence, we can say that the force F as well as the electric field E have the opposite depicting opposite direction. Because, the direction of the lines of an electric field shows that the direction of the electric force experiences positive charge in that particular electric field. Hence, in opposite direction negative charge will be experienced.
