Question

A plumb line is hanging from the ceiling of a car. The plumb line gets inclined at angle α when the car moves with acceleration a, then (A) a = g (B) a = g tan θ (C) a = g cot θ (D) a = g sin θ

Considering the bob to be in equilibrium, we get ma cos θ = mg sin θ i.e. a = g tan θ

Q. A plumb line is hanging from the ceiling of a car. The plumb line gets inclined at angle $α$ when the car moves with acceleration $a$ , then

$a = g$

$a = g tan θ$

$a = g cot θ$

$a = g sin θ$

Considering the bob to be in equilibrium, we get ma cos $θ$ = mg sin $θ$ i.e. a = g tan $θ$

Q. A plumb line is hanging from the ceiling of a car. The plumb line gets inclined at angle α when the car moves with acceleration a, then

a=g

a=gtanθ

a=gcotθ

a=gsinθ
