What will be the gravitational force of attraction between two balls each weighing 5 kg when placed at a distance of 0.33 m apart. (G = 6.673 x 10^-11 Nm2/kg2 )
Correct answer: E. 1.5 x 10^-8 N
- A. 9.1 x 10^-8 N
- B. 7.1 x 10^-8 N
- C. 6.1 x 10^-8 N
- D. 3.5 x 10^-8 N
- E. 1.5 x 10^-8 N
Explanation
Given: m1=5kg m2=5kg r=0.33m G=6.673×10-11 Nm2/kg2 Formula: FG=Gm1m2/r2 FG=(6.673×10-11)(5)(5)/0.332 = 1.5×10-8N
