Answer:

The acceleration of a body moving down a frictionless inclined plane at an angle of 30° = 4.9m/s^{2}

Explanation:

As shown n the figure,

Acceleration of a body moving on a frictionless surface = gsinθ

where, g = Acceleration due to gravity= 9.8m/s^{2}

and given that inclination of the frictionless surface θ = 30°

So,

Acceleration of a body moving on a frictionless surface = 9.8\timessin30°

=9.8 \times \frac{1}{2}

=4.9 m/s^{2}

The correct answer is (a)
