A positive point charge is placed at P in front of an earthed metal sheet S. Q & R are two points between P & S as shown in figure. If the electric field strength at Q & R are respectively EQ& ER and potential at Q & R are respectively VQ&VR . Then-
A
EQ> ER
B
EQ< ER
C
VQ> VR
D
VQ< VR
Explanation
Solution
Ασ ωε αρε αρε μοϖινγ αωαψ φρομ Π τοωαρδ σηεετ Σ σπαχινγ βετωεεν ελεχτριχ λινεσ οφ φορχε ισ ινχρεασινγ. \f0 ER < EQ In direction of electric field potential decreases. \f0 VR < VQ
