During a solar eclipse the moon is positioned directly

Question

Solve the following question given below:

Question: During a solar eclipse the Moon is positioned directly between Earth and the Sun. The masses of the Sun, Earth, and the Moon are 1.99 × 10³⁰ kg, 5.98 × 10²⁴ kg, and 7.36 × 10²² kg, respectively. The Moon\'s mean distance from Earth is 3.84 × 10⁸ m, and Earth\'s mean distance from the Sun is 1.50 × 10¹¹ m. The gravitational constant is G = 6.67 × 10^-11 Nm²/kg².

Part A: Find the magnitude of the net gravitational force acting on the Moon then, due to both Earth and the Sun.

I need help to find the magnitude of the net gravitational force acting on the Moon then, due to both Earth and the Sun.
