A point charge `q = - 8.0 nC` is located at the origin. Find the electric field vector at the point `x = 1.2 m, y = -1.6 m. `

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`E=1/(4piepsilon_0) q/r^3(r_p-r_q)`
`r=sqrt((1.2)^2+(1.6)^2)=2m`
`:. E=((9xx10^9)(-8xx10^-9))/((2)^3)(1.2hati-10.8hati)`
`=0(14.4hati-10.8hatj)N//C`
