Question

A block of mass $m$ slides along a floor while a force of magnitude $F$ is applied to it at an angle $\theta$ as shown in figure. The coefficient of kinetic friction is $\mu_\kappa$. Then, the block's acceleration ' a ' is given by ( g is acceleration due to gravity)

Select the correct option:

A

$-\frac{F}{m} \cos \theta-\mu_k\left(g-\frac{F}{m} \sin \theta\right)$

B

$\frac{F}{m} \cos \theta-\mu_k\left(g-\frac{F}{m} \sin \theta\right)$

C

$\frac{F}{m} \cos \theta-\mu_k\left(g+\frac{F}{m} \sin \theta\right)$

D

$\frac{F}{m} \cos \theta+\mu_K\left(g-\frac{F}{m} \sin \theta\right)$
