Solve this:
Q 29 Suppose the kinetic energy of a body oscillating with
amplitude A and at a distance x is given by k = B x x 2 + A 2 The
dimensions of B are the same as that of -

Dear Student,

As given in the question,
      K=Bxx2+A2writting the dimensions,    ( dimension of work) =(dimension of B) ×(dimension of distance)(dimension of distance)2 ⇒      (dimension of B) = (dimension of work) ×(dimension of distance)

Hence option (2) is correct
