Questions
Radius of a sphere is 100cm at 0°C and 100.1cm at 100°C. Coefficient of cubical expansion of the sphere is
a
30 × 10–6/C
b
10 × 10–6/°C
c
60 × 10–6/°C
d
20 × 10–6/°C
detailed solution
Correct option is A
Given that R1 = 100cm, R2 = 100.1cm; t1 = 00C; t2 = 1000C α=100.1-100100100=10×10-6/0CWe have, thenTalk to our academic expert!
