یہ دو لاشیں غیر صفر کی رفتار کے ساتھ مخالف سمتوں میں آگے بڑھ رہی ہیں ، مندرجہ ذیل میں سے کون سا بیان صحیح ہے؟
- Relative velocity <= Absolute velocity
- Relative velocity = Absolute velocity
- Relative velocity < Absolute velocity
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
When two bodies are moving in opposite directions, their velocities are added to find the relative velocity.
Let's say the velocities of the two bodies are v1 and v2.
Relative velocity = v1 + v2
Since both velocities are non-zero and in opposite directions, the relative velocity will be greater than the absolute velocity of either body.
So, the statement "Relative velocity > Absolute velocity" is true.
