A particle with initial velocity u is moving with uniform acceleration (a). The distance moved by the particle in the `t^(th)` second is given by
`S=u+(1)/(2)a(2t-1)`
The dimensions of S must be

A

L

B

`L T^(-1)`

C

`L T^(-2)`

D

`T^(1)`

Text Solution

Verified by Experts

The correct Answer is:
b
S is the distance travelled in the `t^(th)` second.
`("Distance")/("Time")` = Velocity = `[L^(1)M^(0)T^(-1)]`
All terms have the same dimensions.
They have the dimensions of velocity.
