 Camera cam;
 Rigidbody r;
 Vector3 direction = cam.ScreenPointToRay(Input.mousePosition);
 r.AddForce(direction * 100);

Would just like to modify code shared by @qobion a bit.

Camera cam; Rigidbody r;

//cam assignment cam = GameObject.Find("Main Camera").GetComponent();

//As ScreenPointToRay return a Ray type, it is required to use Ray.direction to get Vector3 direction

Vector3 direction = cam.ScreenPointToRay(Input.mousePosition).direction;

r.AddForce(direction * 100);

No problem. Just adding this for any future reference. I myself was searching for a solution yesterday when I stumbled on this thread.
