Question

write the dimensions of a and b in the relation: E= b-x/at where E,x,t represent energy, distance, time​

Answer 1

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]
