Show answer and explanation
Answer: (A)
अभिकेंद्रीय बल (Centripetal force)
Centripetal force
चंद्रमा लगभग वृत्ताकार कक्षा में इसलिए घूमता है क्योंकि पृथ्वी का गुरुत्वाकर्षण अभिकेंद्र बल का काम करता है। यह बल हमेशा पृथ्वी की ओर लगता है।
The Moon moves in a nearly circular orbit because Earth's gravitational pull acts as the centripetal force. This force always points towards Earth.
