Question

solve it fastttt
......................... distance ?????​

Answer 1

Answer:

the answer is 8.185 m.......

Explanation:

take A 100 kg

B 80kg

then simply use the formula

F=G M × m/ r^2. [r square]

then put the values.......

F= 5×10^-8. [5 into 10 to the power minus 8]

G = 6.7 × 10^-11. [6 point 7 into 10 to the power minus 11]

r (radius) is not known........therefore we have to find out 'radius'

therefore,

the equation sits in this way

"5×10^-8 = 6.7 × 10^-11 × 100×50/r^2

[ five into ten to the power minus eight equals six point seven into ten to the power minus eleven........into 100 into 50 divided by radius square.]

thus......

Step 1:

bring radius square to the side of 5×10^-8

step 2:

then multiply 50 with 100

step3:

bring 6.7×10^-11 under 5×10^-8

step4:

then calculate

step 5:

50000= 5×10^-8/6.7×10-11

this will come

step 6:

you know that if exponents are in a divide form then you have to subtract their powers.........that is [-8-(-11)] = 3.....then take out the point of 6.7 and multiply 10 to it.......then it comes 5×10^4

step 7:

write 50000 in this way

[5 × 10^4]

step 8:

cut 5×10^4/5×10^4

step 9:

this equation remains.....

1/r^2 = 1/67

therefore

..........radius = root of 67

thus radius = 8.185

thank you........ please give at least a thanks
