In the given figure all surface are smooth. Find acceleration of rod.
(A) 5 m/s2
(B) 4 m/s
(C) 6 m/s
(D) None of these​

Answer 1

Answer:

None of the given option

Explanation:

In the given figure all surface are smooth. Find acceleration of rod.

(A) 5 m/s2

(B) 4 m/s

(C) 6 m/s

(D) None of these​

Force acting on road = mg/√2

acceleration = F/m   = mg/√2m

=> acceleration = g/√2

=> acceleration≈ 7 m/s
