Qno.1. Choose the correct option. i. A positively charged glass rod is brought close to a metallic rod isolated from ground. The charge on the side of the metallic rod away from the glass rod will (A) same as that on the glass rod and equal in quantity (B) opposite to that on the glass and equal in quantity (C) same as that on the glass rod but lesser in quantity (D) same as that on the glass rod but more in quantity ii. An electron is placed between two parallel plates connected to a battery. If the battery is switched on, the electron will (A) be attracted to the +ve plate (B) be attracted to the -ve plate (C) move parallel to the plates (D) remain stationary iii. A charge of +7 μC is placed at the centre of two concentric spheres with radius 2.0 cm and 4.0 cm respectively. The ratio of the flux through them will be (A) 1:4 (B) 1:2 (C) 1:1 (D) 1:16 iv. Two charges of 1.0 C each are placed one meter apart in free spac...
