Question

Please someone help me understand this question ​

Answer 1

`\\ \sf\longmapsto F=(Gm_1m_2)/(r^2)`

• m1 and m2 has same units let both be m

`\\ \sf\longmapsto F=(Gm^2)/(r^2)`

`\\ \sf\longmapsto G=(Fr^2)/(m^2)`

SI units:-

• F=Newton (N)
• r=metre(m)
• mass=m=kg

`\\ \sf\longmapsto G=(Nm^2)/(kg^2)`

Option C is correct
