For `SHM` to take place force acting on the body should be proportional to `-x` or `F =- kx`. If `A` be the amplitude then energy of oscillation is `1//2KA^(2)`. Force acting on a block is `F = (-4x +8)`. Here `F` is in newton and `x` in the position of block on x-axis in metersA. Motion of the block is periodic but not simple harmonicB. Motion of the block is not periodC. Motion of the block is simple harmonic about the origin, `x =0`D. Motion of the block is simple harmonic about `x =2m` |
Answer» Correct Answer - D `F =- 4x xx 8`, Let us write `x = (X +2)`, then, `F =- 4X` this is the equation of `SHM`. Further `F =0` as `X =0` or `x =2m` |
