Inducing a Positive Charge on a Sphere
The given below animation depicts the induction procedure. The neutral conducting sphere is at rest on top of an insulating stand. An unhelpfully charged tube is brought near to (without touching) the neutral sphere. The presence of the negatively charged tube forces electron movement from the left to the right side of the sphere. This movement of electrons is just a reaction to the presence of negative charge such as charges repel. At one touched through the ground, the electrons leave the sphere. While the tube is moved away, there is a whole positive charge left on the sphere.
The ratio of specific charge of a proton and an alfa-particle is: (1) 2 : 1 (2) 1 : 2 (3) 1 : 4 (4) 1 : 1 Ans:(1) 2 : 1

Sclera: It is an outer most, thick, impermeable to light. It is more convex and it's front part is transparent is known as Cornea.
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. With reference to a suitable text book, explain
