Telegraph poles occur at equal distances of 220 along a road and heaps of stones are put at equal distances of 300m along the same road. The first heap is at the foot of the first pole. How far from it along the road is the next heap which lies at the foot of a pole?

n poles standing at equal distances on a straight road subtend the same angle alpha at a point O on the road. If the height of the largest pole is h and the distance of the foot of the smallest pole from O is a, the distance between two consecutive poles is

A tower of height b substends an angle at a point O on the leavel of the foot of the tower and at a distance a from the foot of the tower. If a pole mounted on the lower also subtends an equal angle at O, the height of the pole is

Let 10 vertical poles standing at equal distances on a straight line , subtend the same angle of elevation alpha at a point O on this line and all the poles are on the same side of O. If the height of the longest pole is h and the distance of foot the smallest pole form O is alpha then the distance between two consecutive poles, is

Two parallel wires carry equal currents of 10A along the same direction and are separated by a distance of 2.0 cm. Find the magnetic field at a point which is 2.0 cm away from each of these wires.

A pole of 50 meter high stands on a building 250m high.To an observer at a height of 300m, thebuilding and the pole subtend equal angles.The distance of the observer from the top of The pole

A car moving along a straight road with speed of 144 km h^(-1) is brought to a stop within a distance of 200 m. How long does it take for the car to stop ?
