Answer:
D)22.5cm
CB/BA=HG/13.5
CB=15cm,BA=9cm,HG=x and GF=13.5
15/9=x/13.5(divided by 13.5both sides)
x=22.5cm
Answer:
Step-by-step explanation:
According to universal law of gravitation every object in the universe attracts every other particles that surrounds it with a force which is inversely proportional to the square of their distance of separation & directly proportional to
the product of their masses, given by standard formula.
where A,d & G are force of attraction, distance of separation & proportionality constant respectively.
<em>Given:</em>
A1 = 2 units
d1= 5 cm
A2 = 8 units
<em>To find:</em>
Distance of separation when the force of attraction is 8 units d2 = ?
<em>Solution:</em>
Substituting the given values in above at each point,
<em>Answer:</em><em> </em><em>the distance between the two </em><em>objects </em><em>is </em><em>2</em><em>.</em><em>5</em><em> </em><em>cm</em><em>, if the attraction between them is 8 </em><em>units.</em>
