Question

Write the dimensions of a × b in the relation E b-r2 where E is the energy, x is the displacement, at and t is time.​

Answer 1

Answer:

E=atb−x2           E is energy x is displacement t time

E=[ML2T−2]

x=[L]

t=[T]

b will have unit same x2

b=[L2]

a=[Etb−x2]=[ML2T−2×T][L2]=[M−1TL0]

a×b=[L2][M−1L0T]

          =[M−1L2T]
