Two 0.20-g metal spheres are hung from a common point by nonconducting threads which are 30 cm long. Both are given identical charges, and the electrostatic repulsion forces them apart until the angle between the threads is 20 0. How much charge was placed on each sphere? step by step please.

5. (21.68) Two identical spheres with mass m are hung from silk threads of length L, as shown below. Each sphere has the same charge, so qiq2q. The radius of each sphere is very small compared to the distance between the spheres, so they may be treated as point charges. Show that if the angle is small, the equilibrium separation d between the spheres is mg (hint: if θ is small, then tan mass m mass m charge qı charge...

Two identical spheres with mass m = 3.6 × 10-6 kg are hung from silk threads of length L = 0.8 m, as shown in the figure. Each sphere has the same charge, so q1 = q2 = q = 1 nC. The radius of each sphere is very small compared to the distance between the spheres, so they may be treated as point charges. With the approximation of small angles (θ is small so tan theta approximately equal to...

Two small spheres with mass m = 15.3 g are hung by silk threads of length L = 1.21 m from a common point (Figure 1). When the spheres are given equal charges, so that q1=q2=q, each thread hangs at an angle θ = 28.0 ∘ from the vertical. Find the magnitude of q.

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.)

Two metal spheres, each of mass 0.30 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·4.5. with the vertical. If each string is 20 cm long, what is the amount of the charge on each sphere? (Enter the magnitude in nc.) nC

Two identical, 10-g metallic spheres are hung from separate 3-cm strings attatched at the same point on the ceiling. As an equal amount of surplus electrons are added to each sphere, the angle between them grows to 60. At this time, how many excess electrons are on each sphere?
