    Electric flux dΦ through a small area element dS due to an electric field E at an angle θ with dS is : dΦ = E . dS = E dS cos θ Total electric flux Φ over the whole surface S due to an electric field E is ~ ~ ~ ~ Φ = |E . dS = E S cos θ = E . S S Electric flux is a scalar quantity. But it is a property of vector field and area. PS:(~ MEANS arrow for vector sign | MEANS integral sign )

    If I'm right about this,use lens maker formula for case 1:lens in the air and case 2:lens in the water,where the values are correspondingly substituted.The formula is 1/f=(n2-n1/n1)(1/R1-1/R2) ((Please note that units are not considered since both ways you get the same answer as refractive index has no units...)) And also,for both the cases,radii of curvature of the lens is a constant.Therefore,when you divide both the equations you arrive at the answer.The answer is approximately 1.6 (It would be better if you write the steps and do the calculations by yourself as it would help you in understanding the concept pretty easier.)

    Since Charges magnitude are 10×10^minus6 &5×10^minus6 respectively. So electrostatic force=k×q1×q2/r^2=9×10^9×10×10^minus6×5×10^minus6/1^2= 0.45 Newton

    The electrostatic force, also known as the Columb Force is an attractive and repulsive force between particles are caused due to their electric charges. This Columb Interaction is named after the French physicist Charles-Augustin de Coulomb. Electrostatic Force is one of the four fundamental forces of nature. We make use of the Coulomb’s Law to solve the forces created by configurations of charge.

    For example, an electric field due to a wire is said to exhibit cylindrical symmetry, because the electric field strength at a given distance r from the electrically charged wire of infinite length will have the same magnitude at each point on the surface of a cylinder (whose axis is the wire) with radius r.
