Consider the following figures 1 and 2. In figure 1, the mass of the body A in air is 0.2 kg. The mass of the water container (with water in it) is 0.5 kg. In figure 2, when A is completely immersed in the water of the container B, the readings of the respective balances change as shown.What is the value of X?
The value of universal Gravitational constant was first determined by:
A coil of wire of cross-section 0.50 mm2 weighs 75g in air and 65g in water. The length of the coil in cm is
