The only force acting on an object moving along the x-axis is the conservative force given by f(x) = (2.00 n/m)x + (1.00 n/m3)x3. (a) what is the change in potential energy when the object moves from x = 1.00 m to x = 2.00 m? (b) what is the change in kinetic energy when the object moves from x = 1.00 m to x = 2.00 m?

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
