Answer -

Given -

m = 10 kg

\mu = 0.1

g = 10 m/s²

where -

\longrightarrow\mu is the coefficient of kinetic friction.

\longrightarrowm is mass of body.

\longrightarrowg is acceleration due to gravity.

━━━━━━━━━━━━━

To find -

Frictional force \longrightarrowF

━━━━━━━━━━━━━

Formula used -

\boxed{\bf \red {F_k = \mu N}}

\boxed{\bf \pink {N = mg }}

where

\longrightarrowF_k is the kinetic friction.

\longrightarrowm is mass of body.

\longrightarrowg is acceleration due to gravity.

\longrightarrowN is normal force.

\longrightarrow\mu is Coefficient of kinetic friction

━━━━━━━━━━━━━

Solution -

N = mg

N = 10 × 10

N = 100 Newton

━━━━━━━━━━━━━

F = \mu N

F = 0.1 × 100

F = 10N

━━━━━━━━━━━━━

�μ = 0.1

g = 10 m/s²

where -

⟶⟶ �μ is the coefficient of kinetic friction.

⟶⟶ m is mass of body.

⟶⟶ g is acceleration due to gravity.

━━━━━━━━━━━━━

To find -

Frictional force ⟶⟶ �F

━━━━━━━━━━━━━

Formula used -

��=��Fk=μN

�=��N=mg

where

⟶⟶ ��Fk is the kinetic friction.

⟶⟶ m is mass of body.

⟶⟶ g is acceleration due to gravity.

⟶⟶ N is normal force.

⟶⟶ �μ is Coefficient of kinetic friction

━━━━━━━━━━━━━

Solution -

N = mg

N = 10 × 10

N = 100 Newton

━━━━━━━━━━━━━

F = �μ N

F = 0.1 × 100

F = 10N
