Three questions. Please answer with all work used to find the answers.
(1)Two equally charged, 3.549 g spheres are placed with 2.925 cm between their centers. When released, each begins to accelerate at 320.079 m/s2. What is the magnitude of the charge on each sphere?
(2)Object A, which has been charged to +12.39 nC, is at the origin. Object B, which has been charged to -25.5 nC, is at x=0 and y=2.07 cm. What is the magnitude of the electric force on object A?
(3)A 5 cm spring is suspended with a mass of 3.8589 g attached to it which extends the spring by 1.5747 cm. The same spring is placed on a frictionless flat surface and charged beads are attached to each end of the spring. With the charged beads attached to the spring, the spring's extension is 0.0116 m. What are the charges of the beads?

How long will it take you to cover the 99 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.5 m/s relative to the walkway.
Pure-wavelength light passes during a double slit, producing a first-order maximum at an angle of 14.6°. At what angle is the second-order maximum?
A 60 kg skier starts from rest at a height of H = 21 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. avoid the effects of air resistance and assume the ramp is frictionles..
A uniform magnetic field of 0.50 T is directed along the positive x axis. A proton moving with the speed of 60 km/s enters this field. The helical path followed by the proton shown has a pitch of 5.0 mm. find the angle between the magnetic field an..
An airplane has a mass of 1.7x10^6kg and the air flows past the lower surface of the wings at 96 m/s. If the wings have a surface area of 1200m^2, how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
