1 of 1

Understanding +4 | -1

Assertion: The number of significant figures in 0.001 is 1 .

Reason: All zeros to the right of a decimal point and to the left of a non-zero digit are never significant.

View answer and explanation

Correct option: A

If both assertion and reason are true and reason is the correct explanation of the assertion.

Option A (If both assertion and reason are true and reason is the correct explanation of the assertion) is correct because the zeros before the first non-zero digit are not 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
