A 25 kg block is initially at rest.if 75 N force is required to move them what will be the possible values of static friction and sliding friction.

$\huge\underline{\underline{\bf \orange{Answer-}}}$

$\large\underline{\underline{\sf Given:}}$

• Mass of block ( m ) = 25 kg
• Force required to move ( F ) = 75 N

$\large\underline{\underline{\sf To\:Find:}}$

• Static Friction
• Sliding Friction

✪$\large{\boxed{\bf \blue{\mu_{static}=\dfrac{F}{mg}}}}$

$\implies{\sf \mu_{static}= \dfrac{75}{25×10}}$

❏ $\implies{\bf \red{ \mu_{static}= 0.3} }$

$\huge\underline{\underline{\bf \orange{Answer}}}$

❏ Static Friction ${\bf \red{0.3}}$

❏ Sliding friction will be ${\bf \red{zero}}$

$\large\underline{\underline{\bf \red{NOTE-}}}$

Static Friction arise when we push to object from flat surface.

Whereas , Sliding friction arise when we puch an object from inclined surface.
