In the figure, three 7.82 kg spheres are located at distances d₁ = 0.226 m, and d₂ = 0.204 m. What are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the net gravitational force on sphere B due to spheres A and C? (a) Number (b) Number IN M. d₁ A B ∙d₂ Units Units N ° (degrees)

A proton is located at (0, 0, -1.0 x 10-9) m, and an alpha particle (consisting of two protons and two neutrons) is located at (1.0 x 10-9, 0, 2.5 x 10-9) m. (Express your answers in vector form.) (a) Calculate the force the proton exerts on the alpha particle. XN (b) Calculate the force the alpha particle exerts on the proton. X N

An accident victim with a broken leg is being placed in traction. The patient wears a special boot with a pulley attached to the sole. The foot and boot together have a mass of 4.0 kgkg, and the doctor has decided to hang a m� = 6.6 kgkg mass from the rope. The boot is held suspended by the ropes and does not touch the bed. (Figure 1) Determine the amount of tension in the rope by using Newton’s laws to analyze the hanging mass. Assume that ϕ� = 11 ∘∘ .Hint: If the pulleys are frictionless, which we will assume, the tension in the rope is constant from one end to the other.  The net traction force needs to pull straight out on the leg. What is the proper angle θ� for the upper rope?         What is the net traction force pulling on the leg?

A 270-kg object and a 570-kg object are separated by 4.90 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 32.0-kg object placed midway between them. N (b) At what position (other than an infinitely remote one) can the 32.0-kg object be placed so as to experience a net force of zero from the other two objects? m from the 570 kg mass toward the 270 kg mass

5) A book of mass 2Kg and a pen of mass 0.03Kg are in the same room and are separated by a distance d = 5m. a) Do the two object feel any mutual attraction or repulsion? If so, what is the magnitude of that force of attraction orrepulsion? b) What is the relation between the value of the acceleration of gravity |g| = 9.8m/s2 and Newton's law of gravitation?

A 175-kg object and a 475-kg object are separated by 3.30 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 61.0-kg object placed midway between them. N (b) At what position (other than an infinitely remote one) can the 61.0-kg object be placed so as to experience a net force of zero from the other two objects? m from the 475 kg mass toward the 175 kg mass
