Questions
Figure shows a rectangular plate of dimensions (l x b) from which the circular holes of radii r1 and r2 (r1 > r2) has been cut. The distance between the two holes is d (> r2 ). If d' be the respective distance at some higher temperature, then (d'/d) is
detailed solution
Correct option is A
Remember that all the dimensions will increase as the temperature is increased. d′=d(1+αΔT)or d′/d=1+αΔTTalk to our academic expert!
