The distance between tow objects is increased by 3 times the original distance. How will this change the force of attraction bet

lys-0071 [83]

Answer:

force of attraction will be increased by 9

Explanation:

force of attraction is inversely proportional to square of distance

i.e F= 1/R²

F=1/3R²

F=1/9R

multiply both side by 9

9×F= 9×1/9R

9F= 1/R

so force of attraction is 9 times

Tresset [83]

Answer:

The work done is -209.42 J.

Explanation:

F(x) = (- 20 - 3 x ) N

x = 0 to x = 6.9 m

Here, the force is variable in nature, so the work done by the variable force is given by

$W =\int F dx\\\\W =\int_{0}^{6.9}(-20- 3x dx )\\\\W= \left [ - 20 x - 1.5 x^2 \right ]_{0}^{6.9}\\\\W = - 20 (6.9 - 0) - 1.5(6.9\times 6.9 - 0)\\\\W =- 138 - 71.42\\\\W = - 209.42 J$
