Question

Q-2.
d+ c
Find the dimensions of the constants a,b,c and d in the relation v= a+bt +
Where v is velocity and I is time.​

Answer 1

From the principal of homogeneity,

[a]=[v]or[a]=[LT−1]

[bt]=[v]or[b]=[t][v]=[T][LT−1]

or, [b]=[LT−2]

Similarly, [d]=[t]=[T]

Further, [d+t][c]=[v]or[c]=[v][d+t]

or, [c]=[LT−1][T]or[c]=[L]
