Two 1.8-g spheres are suspended by 21.0-cm-long light strings (see the figure). A uniform electric field is applied in the x-direction. If the spheres have charges of −6.0 ✕ 10−8 C and +6.0 ✕ 10−8 C, determine the electric field intensity that enables the spheres to be in equilibrium at θ = 20°. Charged spheres hang from the ends of each of two strings of identical length. The tops of each string are connected to a single attachment point on...
Two metal spheres of identical mass m = 4.60 g are suspended by light strings 0.500 m in length. The left-hand sphere carries a charge of 0.865 µC, and the right-hand sphere carries a charge of 1.49 µC. What is the equilibrium separation between the centers of the two spheres?
Two metal spheres of identical mass m = 3.40 g are suspended by light strings 0.500 m in length. The left-hand sphere carries a charge of 0.845 µC, and the right-hand sphere carries a charge of 1.55 µC. What is the equilibrium separation between the centers of the two spheres?
Two small metallic spheres, each of mass m-0.25 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ-4.80 with the vertical. If each string has length L 38.0 cm, what is the magnitude of the charge on each sphere?
Two small metallic spheres, each of mass m-0.40 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ = 7.5° with the vertical. If each string has length L 28.0 cm, what is the magnitude of the charge on each sphere? nC
Two metal spheres, each of mass 0.55 g, are suspended by massless strings from a common pivot point at the ceiling, as shown in the figure. When both spheres carry the same electric charge, we find that they come to an equilibrium when each string is at an angle of θ = 4.0° with the vertical. If each string is 26 cm long, what is the amount of the charge on each sphere? (Enter the magnitude in nC.)
