215. Write the dimension and hence check the correctness of the following equation(i) v=u+at |
|
Answer» Answer: Here u represents the initial velocity, V the final velocity, a the UNIFORM acceleration, and t the time. The dimensional formula of u is [M LT −1 ]. The dimensional formula of v is [M 0 LT −1 ]. The dimensional formula of at is [M 0 LT −2 ][T]=[M 0 LT −1 ]. Here the dimensions of every term in the given physical RELATION are the same, hence the given physical relation is dimensionally correct. Hope it help u.. |
