An electric field vecE = vec(i20 + vecj3...

An electric field `vecE = vec(i20 + vecj30 ) NC^(-1)` exists in the space. If the potential at the origin is taken to be zero find the potential at (2m, 2m).

Text Solution

Verified by Experts

` E=(i20+j30)N//C, `
` V=at(2m,2m), `
` r=(2i+2j) `
` So, V=-E.r `
` =-(i20+30j).(2i+2j) `
` =-(2xx20+2xx30)=-100V `
