1.	The resultant of two forces has magnitude 20N. One of the forces is of magnitude 20.3Nand makes an angle of 30° with the resultant.Then what is the magnitude of the other force ?a) 10 N b)20 N c) 20.2 N d) 10/3 N
Answer» Answer: 20 N Explanation: Let the other Force be of magnitude X and the angle it MAKES with RESULTANT be θ. Now, the components of the TWO vectors along the resultant should be of magnitude of the resultant and the COMPONENT of these two vectors resolved in the direction perpendicular to resultant should be zero.

Answer»

Answer:

20 N

Explanation:

Let the other Force be of magnitude X and the angle it MAKES with RESULTANT be θ.

Now, the components of the TWO vectors along the resultant should be of magnitude of the resultant and the COMPONENT of these two vectors resolved in the direction perpendicular to resultant should be zero.
