The charge Q₂ is(a) in terms of variables expressed as(b) The magnitude of charge Q₂ = 0.01334 nCGiven two charges Q₁ and Q₂ such thatthe charge on Q₁ = 35 nC = 35×10⁻⁹ CMass of Q₂ is m = 3.5 microgram = 3.5×10⁻⁹ Kgdistance r between the charges = 35 cm = 0.35 m(a)The charge Q₂ is floating because theelectrostatic forceF and the weight W of the charge are balanced, that isF = W(b)The magnitude of Q₂:Q₂ = 13.34×10⁻¹² CQ₂ = 0.01334 nC must be the magnitude of the charge so that it floats.Learn more:brainly.com/question/14870624...
