The variation of potentional with distance r from a fixed point is shown in fig. The magnitude of electric field at r=5cm, is: Share with your friends Share 2 Vaibhav T. answered this Dear Student, Potential has decreased from 5 V to 0 V in 2 cm, i.e., from r=4 cm to r=6 cm linearly.So, E=-∆V∆rE=-0-56-4 V/cmor, E=2.5 V/cm 3 View Full Answer Manish Sakalkar answered this (2.5) V/cm 1
