Answer:

$F_f=7.0035\times 10^{-7}\ N$

$F_j=8.45\times 10^{-6}\ N$

Explanation:

(a)

mass of baby, $m_b=4.2\ kg$

mass of father, $m_f=100\ kg$

distance between father and baby, $d=0.2\ m$

Now, the gravitational force on baby due to father:

$F_f=G \frac{m_b.m_f}{d^2}$

$F_f=6.67\times 10^{-11}\times \frac{4.2\times 100}{0.2^2}$

$F_f=7.0035\times 10^{-7}\ N$

(b)

distance between baby and Jupiter, $r=6.29\times 10^{11}\ m$

We have mass of Jupiter, $m_j=1.898\times 10^{27}\ kg$

Now, the gravitational force on baby due to planet Jupiter:

$F_j=G \frac{m_b.m_j}{r^2}$

$F_j=6.67\times 10^{-11}\times \frac{4.2\times 1.898\times 10^{27}}{(6.29\times 10^{11})^2}$

$F_j=8.45\times 10^{-6}\ N$

We find that the gravitational force due to Jupiter is considerably greater than the force due to mass of father.

We get hurt when we kick a brick however we can displace it easily without pain when it is pushed gently, why?

Alla [95]

You’re using more force to kick the brick than to push it gently.
