Question

correct form of gravitational law is

  1. F equals negative fraction numerator Gm subscript 1 straight m subscript 2 over denominator r squared end fraction
  2. F with not stretchy rightwards arrow on top equals negative fraction numerator Gm subscript 1 straight m subscript 2 over denominator r squared end fraction
  3. F with not stretchy rightwards arrow on top equals negative fraction numerator Gm subscript 1 straight m subscript 2 over denominator r squared end fraction straight r with rightwards arrow on top
  4. F with not stretchy rightwards arrow on top equals negative fraction numerator Gm subscript 1 straight m subscript 2 over denominator r cubed end fraction r with not stretchy rightwards arrow on top

The correct answer is: F with not stretchy rightwards arrow on top equals negative fraction numerator Gm subscript 1 straight m subscript 2 over denominator r squared end fraction straight r with rightwards arrow on top
