Threads Of Silk
Two small spheres of mass m = 14.5 g are suspended by silk son of length L = 1.27 from a common point.?
Two small spheres of mass m = 14.5 g are suspended by silk son of length L = 1.27 from a common point. When the spheres are given loads equal, so that q1 = q2 = q, each thread hangs at an angle of 20 degrees vertical. Find the magnitude of q.
Consider a single sphere, and consider all the forces acting on it. There are three: 1. weight (= mg, the fall) 2. electrostatic repulsion of the other sphere (q = ² / (4πε0r ²). This force is horizontal, because the 2 spheres are on the same horizontal plane. Note that their separation r is equal to 2Lsin (20 °)). 3. The tension T in the net (diagonal up). Since the spheres are in equilibrium, these three vectors of force must be equal to exactly zero. To calculate, it is easier to consider the horizontal and vertical components of the components separately. components down to the top equal components: Weight = vertical component of the "T"; mg = tcos (20 °) to the left equal components to the right components: the repulsion = Horizontal component of the "T" q ² / (4πε0r ²) = Tsin (20 °) Summary: ———- mg = tcos (20 °) ² q / (4πε0r ²) = Tsin (20 °) The rest is algebra. You are given "m" and "r" (remember r = 2Lsin (20 °)), so you're left with two unknowns ("q" and "T"). That's 2 equations to 2 unknown whether the use of the algebra of simultaneous equations to solve.
