Question

In the given figure,,,,,force of 5N acting on object toward East and then it moves towards North under the action of 6N force
the resultant on the object is equal to
A)√32N

B)7N
C)√61N
D)√11 N​

Answer 1

Answer:

Since typing all those formulas were getting cumbersome I just solved it on a piece of paper and uploaded it.

For reference,

I have taken vector A=10N, vector B=8N, the angle between vectors A & B as

θ (theta) = 60 degrees.

The resultant vector is C and at an angle ø (phi) with vector A.

Notice another thing. I have taken ø between vector A and C. If I need to know the angle between vector B and C, say angle α (alpha)

or just α = 60 degrees - θ

Hope that helps.

Answer 2

Answer: C

Explanation: Using Pythagoras Theorem,

R²=√6² +√5²

R=√61
