Question

calculate the force of gravitational due to the earth on a ball of 1 kg mass lying on ground mass of earth 6×10 power 24 distance is 6.4×10 power 3 dravity is 6.6×10 power -11 , find friction​

Answer 1

Answer:

the formula for this question is

F = GmAmB        (mA= mass of earth, mB= mass of ball)

          R2

F = 6.6 x 10⁻¹¹ 6 x 10²⁴ x 1

            6.4 x 10³

=  6.6 x 6 x 10 ⁽⁻¹¹⁺²⁴⁾

       ( 6.4 x 10 ⁶)²

=  3.96 x 10¹³

     40.96 x 10¹²

= 396 x 1000

    40960

= 9.66796875

= so approx. it will be 9.8 newtons
