Answer #1

HERE IS THE SOLUTION

OPTION 2 IS CORRECT

k (5) H() = K (53) (+2) we know + CONS - 0 SO, - ? Ke- (rs)(1-S) +) NOW, 중 - [6this 쓣 (6) (2) - +) (2s+1) ) ds Now if CO 6 -)NOW) when it Break away Point = -5 then K Must Be=o. Now, K:-(S-1) (5+2) (5+3) --66*2)9 2 which is proved Means - 5 is the Brк: - к -2 x | 2. Means Point 50. OPTION-2 ig CORRECT.
