Physics And Measurement Question 260
Question: With the usual notations, the following equation $ S _{t}=u+\frac{1}{2}a(2t-1) $ is
Options:
A) Only numerically correct
B) Only dimensionally correct
C) Both numerically and dimensionally correct
D) Neither numerically nor dimensionally correct
Show Answer
Answer:
Correct Answer: A
Solution:
[a] On $ LHS,S _{t} $ is the distance while on RHS, u is the speed, so it is not dimensionally correct. It is numerically correct only.
