Two poles are separated by a distance of `3.14 m`. The resolving power of humna eye is 1 minute of an arc. The maximum distance from which he can identify the two poles distinctly is .

Two similar equal poles magnetic when separated by a distance of 1m, they repel with a force of 10^(-3)N . The pole strength is

The magnetic induction at a distance 'd' form the magnetic pole of unkown strength 'm' is B . If an identical pole is now placed at a distance of 2d from the first pole, the force between the two poles is

On screen there are two bright points at a distance I mm. These points are observed by the person whose eye is having diameter 3 mm from which maximum distance this person can observe them resolved ?

A : To increase the resolving power of a microscope, .oil immersion objective. can be used. R : Resolving power of the microscope is given by the reciprocal of the maximum separation of two objects distinctly seen.

For the situation of the previous question, find the maximum distance at which the eye would be able to resolve the two headlights of a car which are at a distance of 1.5m .

A man wants to see two poles separately situated at 11 km. The minimum approximate distance between the poles is
