A square loop of side ‘l’ each side having uniform linear charge density ‘lambda’ is placed in ‘xy’ lane as shown in the figure There exists a non uniform electric field E→=al(x+l)iˆ where a and l are constants and x is the position of the point from origin along x-axis. Find the resultant electric force on the loop (in Newtons) if l=10 cmλ=20μ C/m

Two identical small balls each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless, nonconductive walls, the bead move, and at equilibrium the line joining the balls is horizontal and the distance between them is R (see figure). Neglect any induced charge on the hemispherical bowl. Then the charge on each bead is : (here K = 1/ 4πε0)

Four point positive charges are held at the vertices of a square in a horizontal plane. Their masses are 1kg,2kg,3kg,&4kg. Another point positive charge of mass 10kg is kept on the axis of the sqaure. The weight of their fifth charge is balanced by the electrostatic force due to those four charges. If the four charge on the vertices are released such that they can freely move in any direction(vertical, horizontal etc.) then the acceleration of the centres of mass of the four charges immediately after the release is (Use g=10 m/s2)

Two small balls having equal poistive charges Q( coulomb) on each are suspended by two insulating strings of equal length L(metre) from a hook fixed to a stand. The whole set up is taken in a satellite into space where there is no gravity (state of weightlessness). The angle between the two strings is.
