Perpendicular to surface, their acceleration components must be equal. aA cos θ=aB sin θ √21 aA=2 aB <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/42277bfe8301f08415f7cc99ad9512cd-.png" />

$2 a_{A} = 21 a_{B}$

$2 a_{A} = 5 a_{B}$

$5 a_{A} = 2 a_{B}$

$21 a_{A} = 2 a_{B}$

Perpendicular to surface, their acceleration components must be equal.
$a_{A} cos θ = a_{B} sin θ$
$21 a_{A} = 2 a_{B}$

Q. There are two blocks A and B in contact with vertical and horizontal smooth surfaces respectively, as shown in the figure. Acceleration of A and B are aA​ and aB​ respectively along their constrained direction of motions. Relation between aA​ and aB​ is (Assume sin23∘=2/5)

2aA​=21​aB​

2aA​=5aB​

5aA​=2aB​

21​aA​=2aB​

Perpendicular to surface, their acceleration components must be equal. aA​cosθ=aB​sinθ 21​aA​=2aB​

$2 a_{A} = 21 a_{B}$

$2 a_{A} = 5 a_{B}$

$5 a_{A} = 2 a_{B}$

$21 a_{A} = 2 a_{B}$

Perpendicular to surface, their acceleration components must be equal.
$a_{A} cos θ = a_{B} sin θ$
$21 a_{A} = 2 a_{B}$
