FIND THE NORMAL FORCE.......

Classical Mechanics Level 3

Block of mass m is stationary with respect to a smooth wedge. Normal force exerted by wedge on the block is

\frac{mg}{tan\theta}

\frac{mg}{cos\theta}

mg\cos\theta

mg\tan\theta

\frac{mg}{sin\theta}

mg\sin\theta

Forces acting along the inclined plane:

$ma$ $\cos\theta$ = $mg$ $sin\theta$

$\implies$ $a$ = $gtan\theta$

Forces acting normal to the block:

$N$ = $mg$ $cos\theta$ + $ma$ $sin\theta$

$\implies$ $N$ = $mg$ $cos\theta$ + m( $gtan\theta$ ) $sin\theta$

$\implies$ $N$ = $mg$ $cos\theta$ + $mg$ $\frac{sin^2\theta}{cos\theta}$ = $\frac{mg}{cos\theta}$
