Web1. Two uniformly charged spheres, A and B, are placed at a large distance from each other, with their centers on the x axis. The charge on sphere A is q, whereas that on sphere B is 2q. If the electrostatic force on sphere A is Fˆi, that on sphere B is (1) −Fˆi (2) Fˆi (3) −2Fˆi (4) 2Fˆi (5) − 1 2 Fˆi Recall Newton’s third law. 2. Web20540 J. Phys. Chem.

WebThe densities of two solid spheres A and B of the same radii R vary with radial distance r as ρ A (r) = k (R r ) and ρ B (r) = k (R r ) 5, respectively, where k is a constant. The moments of … WebSubstance A has a density of 3 g/cm 3 and substance B has a density of 4 g/cm 3. In order to obtain equal masses of these two substances, what must be the ratio of the volume of A to the volume of B? ... Two solid spheres are made from the same material, but one has twice the diameter of the other. ... Two uniform solid balls, one of radius R ... WebNov 5, 2024 · We can also compare the surface charge densities on the two spheres: E1 = σ1 ϵ0 E2 = σ2 ϵ0 ∴ σ2 σ1 = E2 E1 = R1 R2 ∴ σ2 = σ1R1 R2 and we find that the charge density is higher on the smaller sphere. Thus, there are more charges per unit area on the smaller sphere than the bigger sphere. good soda combinations
