square of side 10 cm with four charges placed at its corners. O is the centre of the square Where, (Sides) AB = BC = CD = AD = 10 cm (Diagonals) AC = BD = 10 square root of 2 cm AO = OC = DO = OB = 5 square root of 2 cm A charge of amount 1μC is placed at point O. Force of repulsion between charges placed at corner A and centre O is equal in magnitude but opposite in direction relative to the force of repulsion between the charges placed at corner C and centre O. Hence, they will cancel each other. Similarly, force of attraction between charges placed at corner B and centre O is equal in magnitude but opposite in direction relative to the force of attraction between the charges placed at corner D and centre O. Hence, they will also cancel each other. Therefore, net force caused by the four charges placed at the corner of the square on 1 μC charge at centre O is zero.

Physics? Anyways. Restrictions of electric vector of light to vibrate in one plane. Like in light it vibrate in all possible direction. In this process we restrict the electric vector. Hence the intensity f light decreases
