1 A The forces we experience in everyday life are electromagnetic in nature except gravity B A glass rod after rubbing with silk glass gets negative charge and silk gets positive charge a A is correct b B is correct c A B are correct d A B are not correct 2 Which of the following are not correct P The atom is electrically neutral and is made up of the positively charged electrons negatively charged protons and neutrons which have zero charge Q Benjamin Franklin argued that when one object is rubbed with another object charges get transferred from one to the other R Charging the objects through rubbing is called tribo electric charging S Most objects in the universe are made up of atoms which in turn are made up of only electrons a only S b only P c only Q d only P S 3 A Glass rod and Silk cloth after rubbing brought nearer will experience repulsive force B Ebonite glass after rubbing with fur and silk brought nearer will experience attractive force a A is correct b B is correct c A B are correct d A B are not correct 4 The number of ve charged electrons in a total charge of 9 6 x 10 coulomb is a 16 b 6 c 6 25 x 10 d 5 5 The magnitude of the electrostatic force between two point charges and separated by a distance of 1 m is a 9 N b 9 x 10 N c 1 6 x 10 N 6 1 kg of two masses are kept in air or inside water the gravitational force between two masses remains the same Why a it is independent of the nature of the medium c Gravitational constant is same 7 Match It P Charge Q electric permittivity R Universal Gravitational constant S electric permittivity of free space a P T Q V R W S U c P V Q T R W S U each of one coulomb in vacuum d 9 x 10 N 9 Which is a uniform electric field b b It is dependent of the nature of the medium d it is not an electromagnetic force TC N m2 U coulomb V Nm C W N m kg b P U Q T R W S V b P U Q V R W S T 8 Two charges 4C and 2 C are experiencing a force of 100 N If a third charge 10 C is added with the above the two charges the new force will be a 1400 attractive b 1400 repulsive c 3200 attractive d 3200 repulsive NO d In of HCl gas is placed in a uniform electric field of magnitude 3 x 104 N C 1 The dipole dlate the maximum torque experienced by
