if a stone of mass 0 05kg is thrown out of a windo
Question:
If a stone of mass 0.05kg is thrown out of a window of a train moving at a constant speed of 100km/h, the magnitude of the net force acting on the stone is:
Show Hint
Constant velocity implies zero net force.

\(0.5\,\text{N}\)
zero
\(50\,\text{N}\)
5N
Show Solution
Verified By Collegedunia
The Correct Option is
B
Solution and Explanation
Step 1:
The train is moving with constant velocity.
Step 2:
Hence acceleration of the stone (horizontally) is zero.
Step 3:
Net force F = ma = 0.
