Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

A 0.75-kg cart is pulled along a horizontal track by a rope. The rope makes an angle
of 30 degrees to the horizontal.
Your friend says that the normal component of the force the track exerts on the cart
is 7.5 N because mg = (0.75kg) (¹0N) = 7.5N.
Do you agree with your friend? Use a force diagram and Newton's 2nd Law to
explain why.
