The diagram shows the forces acting on a cart.
Which statement correctly describes the motion of the cart at this point in time?
A) The velocity is remaining constant because forces F1 and F2 are balanced, and both of these two equal forces are perpendicular to the velocity.
B) The speed of the cart is increasing because forces F1 and F2 are balanced, and both of these two equal forces are perpendicular to the velocity.
C) The speed of the cart is decreasing because forces F4 and F3 are unbalanced, and the greater of the two forces is acting in the opposite direction of the velocity.
D) The direction of the velocity is changing because forces F4 and F3 are unbalanced, and the greater of the two forces is acting in the opposite direction of the velocity.

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.)
