The distance travelled by a body moving ...

The distance travelled by a body moving along a straight line with uniform acceleration (a) in the nth second of its motion is given by `S_(n)=u+(a)/(2)(2n-1)`. This equation is

A

only numerically correct only

B

only dimensionally correct only

C

correct both dimensionally and numerically

D

neither numerically nor dimensionally correct

Text Solution

Verified by Experts

The correct Answer is:
c
This equation is correct both dimensionally and numerically. However if the equation is `S_(n)=u+(a)/(3)(2n-1)` then it is dimensionally correct but numerically wrong.
