Question

Two blocks of mass 6kg and 4kg are pushed along a horizontal frictionless surface by a force of 40N applied to the 6kg block at an angle of 60° to the horizontal. The force that the 4kg block exerts on the 6kg block is <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-ojfvvv4nuuscyvc8.jpg" /> (A) 8N to the left (B) 12N to the left (C) 12N to the right (D) 8N to the right

Acceleration of the system (a) =20/10m/s2=2m/s2 Force by 4kg block on 6kg block = force by 6kg block on 4kg block =4× 2N=8N =4× 2N=8N

Q. Two blocks of mass $6 k g$ and $4 k g$ are pushed along a horizontal frictionless surface by a force of $40 N$ applied to the $6 k g$ block at an angle of $6 0^{\circ}$ to the horizontal. The force that the $4 k g$ block exerts on the $6 k g$ block is

$8 N$ to the left

$12 N$ to the left

$12 N$ to the right

$8 N$ to the right

Acceleration of the system (a) $= 20/10 m / s^{2} = 2 m / s^{2}$
Force by $4 k g$ block on $6 k g$ block
$=$ force by $6 k g$ block on $4 k g$ block $= 4 \times 2 N = 8 N$
$= 4 \times 2 N = 8 N$
