Two blocks of masses

2\,\text{kg}

and

3\,\text{kg}

are in contact on a smooth horizontal surface. A horizontal force of

10\,\text{N}

is applied on the

2\,\text{kg}

block toward the right. Find the magnitude of the force exerted by the

2\,\text{kg}

block on the

3\,\text{kg}

block. (a)

10\,\text{N}

(b)

4\,\text{N}

(c)

6\,\text{N}

(d)

15\,\text{N}
