    Answer:

    Explanation:

    Formula

    Force = G * m1 * m2 / r^2

    Givens

    • F = 1.67 * 10 – 9 N
    • G = 6.67 × 10-11 Newtons kg-2 m2.
    • m1 = 110 kg
    • m2 = ?
    • r = 11 meters.

    Solution

    1.67 * 10^-9 = 6.67 * 10^-11 * 110 * m2/(11)^2        Divide both sides by 10^-9

    1.67 * 10^-9/10^-9 = 6.67*10^-11/(10^-9 *110*m2/121

    1.67 = 6.67 * 110 * 10^-2 * m2 / 121                      Multiply both sides by 121

    1.67 * 121  = 6.67 * 10 ^-2 * 110 * m2 * 121/121      Combine

    202.07 = 7.337 * m2                                           Divide both sides by 7.337

    202.07/7.337  =  m2

    m2 = 27.54 kg
