Which action is due to field forces?Select one of the options below as your answer: A. an apple falling from a tree B. a moving car stopping when the brakes are applied C. the rowing of a boat D. pushing a chair against the wall

Answers

Answer 1

Answer: Field force is when the force which you exert on prticular subject acts only on this subject, other subjects that sorround yours are not included, whereas the like gravity acts equally on everything. So the correct answer is D. pushing a chair against the wall.

Answer 2

What is the minimum coeffecient of static friction μmin required between the ladder and the ground so that the ladder does not slip?

Answers

Answer:

$\mu = (1)/(2tan\theta)$

Explanation:

let the ladder is of mass "m" and standing at an angle with the ground

So here by horizontal force balance we will have

$\mu N_1 = N_2$

by vertical force balance we have

$N_1 = mg$

now by torque balance about contact point on ground we will have

$mg((L)/(2)cos\theta) = N_2(L sin\theta)$

so we will have

$N_2 = (mg)/(2tan\theta)$

now from first equation we have

$\mu (mg) = (mg)/(2tan\theta)$

$\mu = (1)/(2tan\theta)$
