Physics a level exam question

Asteroid P approaches the two stars G and H. Figure 6 shows one position of P close to H The gravitational force on P from G is 6.38 x 1012 N. The mass of H is 3.00 x 1025 kg and the mass of P is 2.00 × 10^20 kg gravitational field strength at its surface is 0.4 and has radius of 182619 m. The distance HP is 1.50x 10^11 m. Calculate the magnitude of the acceleration of P

Do you have a picture of the question so I can see the positions of the stars and P

Asteroid P approaches the two stars G and H. Figure 6 shows one position of P close to H The gravitational force on P from G is 6.38 x 1012 N. The mass of H is 3.00 x 1025 kg and the mass of P is 2.00 × 10^20 kg gravitational field strength at its surface is 0.4 and has radius of 182619 m. The distance HP is 1.50x 10^11 m. Calculate the magnitude of the acceleration of P

Without seeing the positions of the stars G and H, it would be difficult to advise on how to solve the problem specifically.
However, the general guidelines could be as follow:
1. Draw the direction of gravitational force on P from G on the figure.
2. Determine the gravitational force between P and H and then draw the direction of gravitational force on P from H on the figure.
3. Determine the resultant force on P and then use Newton’s 2nd law to find the acceleration.
