Q.2 Represent graphically the variation of electric field with distance, for a uniformly charged plane sheet.

Q.3 How will the radius of a flexible ring change if it is given positive charge?

Q.4 Five Charges of equal amount (q) are placed at five corners of a regular hexagon of side 10 cm. What will be the value of sixth charge placed at sixth corner of the hexagon so that the electric field at the centre of hexagon is zero ?.

Q.5 Two conducting spheres of radii r₁ & r₂ are at same potential. What is the ratio of charges on the spheres?.
