Question

A particle is projected from the earth's surface, at the topmost point of its path, the particle has an acceleration of magnitude

• A. $\frac{g}{2}$
• B. g
• C. 2g
• D. zero

Answer 1

The correct option is B

g

1. When an object is projected upwards, it is constantly acted upon by the gravitational force of the earth.
2. At the highest point, its acceleration will only be caused by the force of gravity, and the object starts to fall freely towards the surface of the earth.
3. So the acceleration of the particle at the highest point will be equal to the value of $g\left(or\right)9.8m/s^2$.

Hence, the answer is (B) g
