Explanation / Answer

since F=GMm1/r2 GM is fixed for a massiver object. A. m1/r2 = (1/2)m/R2 =m/2R2 B. m1/r2 = m/(R/2)2 =4m/R2 C. m1/r2 = m/(3R)2 =m/9R2 D. m1/r2 = m/(2R)2 =m/4R2 E. m1/r2 = 2m/(R/2)2 = 8m/R2 E has greatest force since F = m1a = m1v2/r =>v2 = F*r/m1 consider: F*r/m1 ˜( m1/r2)r /m1= 1/r A. 1/2R B. 2/R C. 1/3R D. 1/2R E. 2/R B and E has the greatest speed. E has greatest force since F = m1a = m1v2/r =>v2 = F*r/m1 consider: F*r/m1 ˜( m1/r2)r /m1= 1/r A. 1/2R B. 2/R C. 1/3R D. 1/2R E. 2/R B and E has the greatest speed. A. 1/2R B. 2/R C. 1/3R D. 1/2R E. 2/R B and E has the greatest speed.
