N - mg cos 60°=ma cos 60° N=m cos 60° (a+g)=400 N <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/4e601eb305fed3d7c132359d160206c1-.png" /> Reading will be 40 kg

Q. An elevator is accelerating upwards with an acceleration of $6 m / s^{2}$ . Inside it a person of mass $50 k g$ is standing on a weighing machine which is kept on an inclined plane having angle of inclination $6 0^{\circ}$ The reading of the weighing machine is:

$40 k g$

$160 k g$

$80 k g$

$50 k g$

$N - m g cos 6 0^{\circ} = ma cos 6 0^{\circ}$

$N = m cos 6 0^{\circ} (a + g) = 400 N$

Reading will be $40 k g$
