Question:
Planck's constant has the same dimensions
Planck's constant has the same dimensions
Show Hint
The dimension of Planck's constant is force × time, which corresponds to the dimensions of action in quantum mechanics.
Updated On: Oct 8, 2025
- force × time
- force × distance
- force × speed
- force × distance × time
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Planck's Constant Dimensions.
Planck's constant, \( h \), has the dimension of action, which is defined as energy × time. The energy has dimensions of force × distance, so Planck's constant has the dimension of force × time.
Step 2: Conclusion.
Thus, the correct answer is ( force × time.
