]shows the potential energy of a 500 g particle as it moves along the x-axis. suppose the particle's mechanical energy is 12 j. a. where are the particle's turning points? b. what is the particle's speed when it is at x = 6.0 m? c. what is the particle's maximum speed? at what position or positions does this occur? d. write a description of the motion of the particle as it moves from the left turning point to the right turning point. e. suppose the particle's energy is lowered to 4.0 j. describe the possible motions.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
