IB Physics D1 (November 2025 Past Paper 1A TZ1 HL-24, SL-18). Gravitational field lines.
A space probe moves in a gravitational field. No other forces than the gravitational force act on the probe. At one instant, the probe is at point P. The diagram shows the path of the probe and the gravitational field line through P. What is the direction of the acceleration of the probe at P?
