Answer: The answer will be R1 = B

Explanation:

Cause Here x component of A = A

X component of 2B       = 2BcosФ

X component of Resultant = 0

I.e. A + 2BcosФ = 0

cosФ = -A/2B

also R1 = √(A² + B² + 2ABcosФ)

            =√ [A² + B² + 2AB(-A/2B)]

            =√A² + B² -A²

R1 = √B²

R1 = B so R1 = B is correct.
