Explanation Write the expression for Electric field. E = σ 2 × ε 0 Here, E is the electric field, ε 0 is permittivity of free space and σ is the surface charge density. Write the expression for electric force. F = q × E Here, F is the electric field and q is the net charge. Write the expression for the weight of the object. W = m × g Here, W is the weight of the object, m is the mass of the object and g is acceleration due to gravity. Styrofoam piece floats above the plastic sheet, therefore the plastic sheet has negative surface charge density and that its electric field is acting downwards. The electric force on the object acts vertically upwards and counter balances the weight of Styrofoam, therefore, F = W q × E = m × g q × σ 2 × ε 0 = m × g σ = m × g × 2 × ε 0 q (I) Substitute 8.85 × 10 − 12 C 2 / N ⋅ m 2 for ε 0 , 10 g for m , 9
