14. Action and reaction :- (For a given system)
(a) Act on the two different objects
(b) Have opposite directions
(c) Have equal magnitudes
(d) Have zero resultant
(1) a, b, c
(2) b, c, d
(3) All of the above (4) None of the above​

Answer 1

Answer:

3option all the above

Explanation:

1. Opposite dirction, one is positive and one is negative
2. Because modulas of neagative is positive and modulus of positive is positive
3. Because resultant which have same magnitude is zero
4. Because action nd reaction acts on two different objects

Answer 2

Answer:

3

Explanation:

Yes, it is always true that action and reaction act on two different objects.It cannot act on a same object.

Also they are always equal in magnitude.

And since they are always in opposite direction , the angle between action and reaction is 180,hence their resultant will always comes to zero.
