The force exerted by the ideal string on the ideal pulley P shown in the figure is <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-sh0qxs56pyegsz3q.jpg" /> (A) mg (B) 2 mg (C) √2mg (D) 4 mg

Tardigrade Admin · Accepted Answer

As T = mg and for pulley P , we can write Tn e t =√T2 + T2 + 2 . T . T . c o s 120 ° = T = mg

Q. The force exerted by the ideal string on the ideal pulley $P$ shown in the figure is___

$m g$

$2 m g$

$2 m g$

$4 m g$

As $T = m g$ and for pulley $P$ , we can write
$T_{n e t} = T^{2} + T^{2} + 2. T . T . cos 12 0^{\circ} = T = m g$

Q. The force exerted by the ideal string on the ideal pulley P shown in the figure is___

mg

2mg

2​mg

4mg

As T=mg and for pulley P , we can write Tnet​=T2+T2+2.T.T.cos120∘​=T=mg
