\blue{\bold{\underline{\underline{Answer:}}}}

\green{\tt{\therefore{F=6.67\times 10^{-9}\:N}}}

\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}

\green{\underline \bold{<klux>GIVEN</klux> :}} \\  \tt:   \implies Mass \: of \: ball( M_{1}) = 1 \: kg \\  \\ \tt:   \implies Mass \: of \: ball( M_{2}) = 1 \: kg \\  \\ \tt:   \implies Distance \: between  \: radius \: of \: balls (R)= 10 \: cm \\  \\ \tt:   \implies Value \: of \: G = 6.67 \times  {10}^{ - 11} N {m}^{2}  {kg}^{ - 2}  \\  \\ \red{\underline \bold{To \: Find :}} \\  \tt:  \implies Force \: of \: attraction(F)= ?

ACCORDING to given QUESTION :

\bold{As \: we \: know \: that} \\  \tt:  \implies F=  \frac{G M_{1} M_{2}  }{ {R}^{2} }  \\  \\ \tt:  \implies F=  \frac{6.67 \times  {10}^{ - 11} \times 1 \times 1 \times  }{(0.1)^{2} } \times  \frac{N \times {m}^{2}  \times  {kg}^{ - 2}  \times kg \times kg }{ {m}^{2} }   \\  \\ \tt:  \implies F =  \frac{6.67 \times   {10}^{ - 11}   }{0.01}  \times  N \times  {kg}^{ - 2}  \times  {kg}^{2}  \\  \\ \tt:  \implies F=   \frac{6.67 \times  {10}^{ - 11} }{1^{ - 2} }  \times N \\  \\ \tt:  \implies F=  6.67 \times  {10}^{ - 11 + 2}  \: N \\  \\  \green{\tt:  \implies F= 6.67 \times 10^{ - 9}  \: N} \\  \\   \green{\tt \therefore Attraction \: force \: between \: two \: balls}  \\    \:  \:  \:  \: \green{\tt is \: 6.67 \times  {10}^{ - 9}  \: N}
