JEE Mains Model Paper 16

A glass rod of diameter d1 is inserted symmetrically into a glass capillary with inner diameter d2 (d2 > d1). Then the whole arrangement is vertically oriented and brought in contact with the surface of water. The height to which water will risein the capillary... (Given surface tension of water is T, density of water is ‘ρ’ and contact angle between water and glass is 0°).
