Physics · Surface Tension
Liquid A has half the surface tension and twice the density of liquid B at 30°C. The contact angles of A and B with the capillary tube are the same. If liquid A rises to a height of 10 cm in a capillary tube, then the rise (in cm) of liquid B in the same capillary tube at the same temperature will be:
- 120
- 240✓
- 310
- 460
