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.

A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mA = 405 kg and makes his way over the ledge (see the figure below). If the coefficient of static friction between the rock and the ground is H=0.348, and the mass of the hiker is ma= 70.1 kg, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. (ANS: 70.8 kg)

You are a bully. You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground. Your arm is extended so that it makes an angle 28 degrees with the horizontal. The dweeb's back is so sweaty with fear that there is no friction between his back and the wall. What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below. Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)
