Question

Q11: Write the dimensions of a and b in the relation
E = b - x
at
Where Ex and t represent energy, distance and time repectively.
​

Answer 1

The equation is not dimensionally correct. Pls check it out

Answer 2

According to the principle of homogeneity of dimensions, [E] = [b] = [(x2/a) t] [E] = [M L2 T−2] Therefore [b] = [M L2 T−2] Now [E] = [(x2/a) t] = [L2 T /a] ⇒ [a] = [L2 T /E] = [L2 T /(M L2 T−2)] = [ T3/M] Therefore [a] = [M−1 T3]
