Two point charges a and b whose magnitude are same, positioned at a certain distance along the positive x-axis from each other a is at origin. Graph is drawn between electrical field strength and distance x from a. E is taken positive if it is along the line joining from a to b From the graph it can be decided that

Two point-like charges a and b whose strengths are equal in absolute value are positioned at a certain distance from each other. Assuming the field strength is positive in the direction coinciding with the positive direction of the r axis, determine the signs of the charges for each distribution of the field strength between the charges shown in Figures (a), (b), (c), and (d).

Two equal like charges are positioned at a certain distance from each other. How do the electric field strength and the potential vary along the axis that passes through the midpoint of the distance between the charges at right angles to the line connecting the charges?

Two positive point charges Q and 4Q are separted by a distance of 12 cm and from each other. The distance of the neutral point from Q is

A is a point on the positive x-axis at a distance 3 units from the origin and B is a point on the positive y-axis at a distance 4 units from the origin. If P divides AB in the ratio 1 : 2, the coordinates of P are

Find the equation of the circle whose radius is 5 and centre lies on the positive side of x-axis at a distance 5 from the origin.

Find the equation of the circle whose radius is 5 and centre lies on the positive side of x-axis at a distance 5 from the origin.

Two point charges are kept at a certain distance from one another. The graph represents the variartion of the potential along the straight line connecting the two charges. At what point is the electric field zero ?
