The gravitational field in a region is given by `vecE=-(20Nkg^(-1))(hati+hatj)`. Find the gravitational potential at the origin `(0,0)` in `J kg^(-1)`
Text Solution
Verified by Experts
We know the relation between field and potential `V=-intE.dr=[intE_(x).dx+intE_(y).dy]=20x+20y` `impliesV=0` at the origin `(0,0)`
