                   Time Allowed: Three Hours                    maximum Marks: 200
Candidates should attempt Questions I and 5 which are compulsory and any THREE of the remaining Questions, selecting at least ONE questions from each section. If any data is considered insufficient, assume suitable values. Newton may be converted to kg using the equality 1 kilonemwton (1kN) = 100 kg, if found necessary.

(d)  To find out th3e height of a tall building, two ranging rods of height 1.5m and 1.0 m were used. The ranging rods were placed on a line ranged out from the corner of the building such that the distance from the corner of the building to the longer ranging rod was 50 m and to the shorter rod was 60m and the tops of both the ranging rods were in line with the top of the building. Find the height of the building.
