Choose the correct statements :- (a) The tangent drawn at any point on the line of force gives the direction of the force acting on a positive charge at that point (b) The normal drawn at any point on the line of force gives the direction of the force acting on a positive charge at that point (c ) Electric lines of force start from a negative charge and end on a positive charge (d) Electric lines of force start from a positive charge and end on a negative charge

If each line of a pair of lines passing through origin is at a perpendicular distance of 4 units from the point (3,4) then the equation of the pair of lines is

STATEMENT-1 : The electric field lines either originate from or terminate on conducting surface normally . STATEMENT-2 : The number of lines of forces that originals from or terminate on a charge is proportional to the magnitude of the charge. STATEMENT -3 : The field lines always start on positive charges and terminate on negative charge.

If each line of a pair of lines passing through origin is at a perpendicular distance of 4 units from the point (3, 4) , then the equation of the pair of lines is

The equation of the line which is at 10 units from the origin and the normal from the origin to it makes as angle (pi)/(4) with the X-axis in the negative direction is
