Water rises in a vertical capillary tube upto a length of 10 cm. If the tube is inclined at 45°, the length of water risen in the tube will be

The correct answer is (b) 10√2 cm Explanation:  When the tube is inclined, the vertical rise remains the same. So the water in the inclined tube rises to 10*sec45° =10√2 cm.

A wooden block of mass 0.5 kg and density 800 kg/m^3 is fastened to the free end of a vertical spring of spring constant 50 N/m

(a) The volume of wooden block = 0.5/800 m³  =0.000625 m³  The force of buoyancy =0.000625*1000 kg =0.625 kg  The Net force on the block in the water =0.625-0.500 kg-weight  =0.125*10 N {Taking g =...
