Question

A box of mass 5 kg is pulled by a cord, up along a frictionless plane inclined at $3 0^{\circ}$ with the horizontal. The tension in the cord is 30 N . The acceleration of the box is (Take $g = 10 m s^{- 2}$ )NEET 2024 (Re-NEET)

Options:

Answer:

D

Solution:

$T - M g sin 30 = M a$
$30 - 5 \times 10 \times \frac{1}{2} = 5 a$ $a = 1 m / s^{2}$

TestHub · Accepted Answer

T − M g sin 30 = M a 30 − 5 × 10 × 2 1 ​ = 5 a a = 1 m / s 2
