Internal forces acting within a system of particles can alter

A

The linear momentum as well as the kinetic energy of the system

B

The linear momentum of the system, but not the kinetic energy of the system

C

The kinetic energy of the system, but not the linear momentum of the system

D

Neither linear momentum nor kinetic energy of the system

Solution

(c)

The kinetic energy of the system, but not the linear momentum of the system as $F_{\text {ext }}=0$. So momentum will be conserved
