Water rises in a capillary tube to a certain height such that the upward force due to surface tension is balanced by 75×10-4 N force due to the weight of the liquid. If the surface tension of water is 6×10-2 Nm-1, the inner circumference of the capillary must be

(a) 1.25×10-2 m                    (b) 0.50×10-2 m

(c) 6.5×10-2 m                      (d) 12.5×10-2 m
