Question

22. Given M is the mass suspended from a spring
of force constant. k. The dimensional formula
for [M/k] is same as that for​

Answer 1

Explanation:

We know,

F = kx ( neglecting - ve sign)

=> ma = kx

= m/k = x / a.

Thus, dimension of LHS would be same as that of RHS.

x/a =

$\frac{l}{l {s}^{?- 2} }$

thus, unit = T² Ans.
