A 1 kg particle strikes a wall with velocity 1 m/s at an angle $$30^{\circ}$$ and reflects at the same angle. If it remains in contact with wall for 0.1 s, then the force is

Correct option is B. $$10\sqrt{3}$$ N
$$f = $$ Rate of change of momentum.

$$f = \dfrac{mV_{final} - mV_{initial}}{t} $$

$$f = \dfrac{2\times\dfrac{\sqrt{3}}{2}}{0.1}$$

$$f = 10\sqrt{3}$$ N

Correct option is B. $$10\sqrt{3}$$ N
$$f = $$ Rate of change of momentum.

$$f = \dfrac{mV_{final} - mV_{initial}}{t} $$

$$f = \dfrac{2\times\dfrac{\sqrt{3}}{2}}{0.1}$$

$$f = 10\sqrt{3}$$ N
