The following observations were taken for determining surface tension T of water by capillary method : diameter of capillary, D=1.25×10 −2 m rise of water, h=1.45×10 −2 m. Using g=9.80m/s 2 and the simplified relation. T= 2 rhg ​ ×10 3 N/m, the possible error in surface tension is closest to : D=1.25×10 −2 m [...]

A sonometer wire when vibrated in full length has frequency n. Now, it is divided by the help of bridges into a number of segments of lengths l1,l2,l3… when vibration these segments have frequencies n1,n2,n3,,, Then, the correct relation is A sonometer wire when vibrated in full length has frequency n. Now it is divided [...]
