Assertion: The number 1.202 has four significant figures and the number 0.0024 has two significant figures.
Reason: All the non-zero digits are significant.

View answer and explanation

Correct option: B

If both assertion and reason are true but reason is not the correct explanation of assertion

Option B (If both assertion and reason are true but reason is not the correct explanation of assertion) is correct because both statements are true, but the reason does not fully explain the assertion as embedded zeros are also significant.

The method of dimensional analysis can be used to derive which of the following relations? Statement-I: Dimensions of constant of proportionality of constants can be derived from dimensional method
Statement-II: Numerical value of constant of proportionality can be found from experiments only The dimensions of torque are The physical quantity having the dimensions

\left[ {{\mathrm{M}^{ - 1}}{\mathrm{L}^{ - 3}}{\mathrm{A}^2}{T^3}} \right]

is A quantity X is given by

{\varepsilon _0}L\frac{{\Delta V}}{{\Delta t}},\;

{\varepsilon _0}

is the permittivity of free space, L is a length,

{\Delta V}

is a potential difference and

{\Delta t}

is a time interval. The dimensional formula for X is the same as that of
