Question

The dimensions of a×b in the relation E=b-x²/at. where E is the energy, x is distance and t is time.

Answer 1

Answer:

Explanation:

E = ( b -x²) /at= ( b/at - x²/at)

where E = energy

t = time

x = displacement.

so,

dimension of E = dimension of { b/at }b/at = E

b/a = Et

dimension of {a/b} = 1/Et = 1/[ ML²T-²][ T]    = [ M-¹ L-²T]
