A uniform thin wire of linear mass density `lambda` and it's length is infinity placed on the +y axis and its one end at the origin as shown. The Magnitude and direction of the gravitational field intensity at the point (R, 0) on X-axis is
| A. |
`(sqrt2Glambda)/R 45^o` , with positive x-axis in anticlockwise direction |
| B. |
`(sqrt2Glambda)/R,135^o` with positive x-axis in anticlockwise direction |
 |
| C. |
`(Glambda)/R,45^o` with positive x-axis in anticlockwise direction |
| D. |
`(Glambda)/R,135^o` with positive x-axis in anticlockwise direction |
Selection the strip field and then integrate the `E_x=(G lambda)/R` along -x -axis
`E_y=(G lambda)/R` along -y -axis
Hence the resultant gravitational field intensity. `(sqrt2 G lambda)/R , 135^o` with +ve x-axis in anticlock wise direction.
