Answer:

F = 2.668*10_-6[N]

Explanation:

We can calculate this force using the law of universal gravitation raised by Isaac Newton

$m_{t}=20000[kg]\\m_{c}= 200[kg]\\r = 10[m]\\G = 6.67*10^{-11}[\frac{N*m^{2} }{kg} ] \\$

And the force is given by the following expression:

$F=G*\frac{m_{t}*m_{c}}{r^{2} } \\F=6.67*10^{-11} *\frac{20000*200}{10^{2} }\\F=2.668*10^{-6} [N]$

Answer:

d) 4a

Explanation:

r = Distance

Electrostatic force is given by

$F=\dfrac{kq_1q_2}{r^2}$

$ma=\dfrac{kq_1q_2}{r^2}$

It can be seen that the force is inversely proportional to distance

$a\propto \dfrac{1}{r^2}$

If the distance is reduced

$\dfrac{a_1}{a_2}=\dfrac{r_2^2}{r_1^2}\\\Rightarrow \dfrac{a_1}{a_2}=\dfrac{(\dfrac{d}{2})^2}{d^2}\\\Rightarrow \dfrac{a_1}{a_2}=\dfrac{1}{4}\\\Rightarrow a_2=4a_1$

So, the new acceleration will be four times the old acceleration

The answer is d) 4a
