Answer:
The answer is D.
Explanation:
Look at these options. Do all of these require effort? Yes. If you were to push a shopping cart, do you have to apply force? if you were to lift a book, do you indeed move the book, does it exert force? While walking up stairs, do you have to move your legs uphill, is there force used? All of these require input, and force. Most things in life require work, unless we have a machine to do it for us.
Answer:No
Explanation: No, If forces are being applied to the object the object will not remain at rest.

Yoga- It benefits muscular strength as well as core balance and flexibility.
It also improves respiration, energy and vitality.
solution:
E\delta =\frac{R}{\epsilon0}(1-\frac{A}{\sqrt{4R^{2}}-ac}
=\frac{R}{\epsilon0}(1-\frac{1}{\sqrt{4r^{2}/^{_a{2}}+1}})
=\frac{R}{\epsilon0}(1-\frac{1}{\sqrt{4x^2+1}})
x=\frac{r}{a}
infinite case,
Ei=\frac{r}{\epsilon0}
\therefore e\delta =ei(1-\frac{1}{\sqrt{4x^{2}+1}})
we have to find x when,
ei-e\delta =1% ,y=ei=1/100 ei
or,ei-ei+\frac{ei}{\sqrt{4x^2+1}} = 1/100ei
\frac{1}{\sqrt{4x^2+1}}=\frac{1}{100}
4x^2+1 =10^4
x=\frac{\sqrt{\frac{10^4-1}{4}}}=49.99\approx 50
\therefore \frac{r}{a}\approx 50
