The gravitational field in a region is given by vecE = (2hati+3hatj) N/Kg. The workdone by the field when the particle is moved on the line 3y + 2x = 5

Answer»

Solution :`vecE=2hati+3hatj`
The FIELD is represented as
Slope `m_1 = Ttantheta_(1)=3//2`
The line 3Y + 2X = 5 can be represented as
Slope `m_2=Tantheta_(2)=-2//3`
`m_(1)xxm_2=-1`
Since, the DIRECTION of the field and displacement are PERPENDICULAR the workdone by the field on the particle is zero.
