# The Solar constant is defined as the energy incident per unit area per second. The dimensional formula for solar constant is

$[ML^0T^{-3}]$

##### SOLUTION
Energy incident per unit area, per second in dimensions
$\displaystyle =\dfrac {Energy}{Area\times second}=\dfrac {ML^2T^{-2}}{L^2T}=ML^oT^{-3}$

Q1 Single Correct Medium
A highly rigid cubical block $A$ of small mass $M$ and side $L$ is fixed rigidly on to another cubical block of same dimensions and of low modulus of rigidity $\eta$ such that the lower face of $A$ completely covers the upper face $B$. The lower face of $B$ is rigidly held on a horizontal surface. A small force $F$ is applied perpendicular to one of the side face of $A$. After the force is withdrawn, block $A$ executes small oscillations, the time period of which is given by :
• A. $2\pi \sqrt{M\eta L}$
• B. $2\pi \sqrt{\dfrac{M\eta}{ L}}$
• C. $2\pi \sqrt{\dfrac{ML}{\eta}}$
• D. $2\pi \sqrt{\dfrac{M}{L\eta}}$

Q3 Subjective Medium
The pressure on a square plate is measured by measuring the force on the plate and the length of the sides of the plate by using the formula $P = F/l^2$. If the maximum errors in the measurement of force and length are $4\%$ and $2\%$, respectively, then what is the maximum error in the measurement of pressure?
