Test 1 Online 13 It is observed that as one moves along positive x axis the electrostatic potential reduces One may conclude that the direction of electric field 1 Must be along x axis 2 Must be perpendicular to x axis 3 May be perpendicular to x axis 4 May be along x axis 14 A parallel plate capacitor has a uniform electric field E in space between the plates If the distance between the plates is d and area of the plate is A the energy stored in the capacitor is 1 EAd 3 E Ad 4 E 15 A capacitor of capacitance C is charged upto 90 V and then connected to an uncharged capacitor of capacitance 2C The final potential difference across each capacitor will be 1 45 V 3 90 V 16 In a certain region potential is given by V K 2xy The electric field at 1 1 has magnitude 1 2 k 2 2 2 k Medical 3 k 2 1 2 30 V 4 60 V 17 The variation of electrostatic potential as a function of distance from a point charge is best represented by X 12 ITutor All India Aakash Test Series for NEET 2021 18 On an insulated rod of length charge Q is uniformly distributed and a point charge q is placed at a distance d from one of its ends as shown The electric force on q is Q 2 3 K qQ 4d d c 9Q 4 9Q n Foundations 4TE X d Divisions of ash A4 C charge is placed in some gaussian surface such that outward flux is 6 What additional charge is needed to be placed inside the surface such that there is net inward flux of magnitude 66 1 6 C 2 14 C 3 28 C 4 10 C 20 When a polythene is rubbed with wool it develops a charge 3 2 x 10 7 C The number of electrons transferred is 1 2 10 3 10 d X 2 8 x 10 0 4 2 x 10 2
