Can we arrange voltmeters like this? 
Can we arrange two voltmeters like this?
I have no idea about this, like how it works and if it is a correct orientation.
And for my work I only know that it is correct and it reads the potential difference (both share/divide the readings with each other as per their internal resistance).
EDIT:- Please note that the voltmeter is not ideal
 A: Voltmeters are used to measure the potential difference across given circuit elements (e.g., resistors).  Since a voltmeter is also a circuit element, the measurement of potential difference (aka voltage drop) should not be significantly affected by putting the voltmeter in the circuit.  Accordingly, voltmeters are always placed parallel to the circuit element whose resistance you are measuring, and they have a very high resistance to ensure that they do not significantly affect the measurement when providing a parallel circuit path for current to flow.  This means that voltmeters should never be placed in a series configuration in a circuit, because their very high resistance will lead to a very low current flow in the circuit, and the resulting measurement will provide information about the resistance of the voltmeter rather than the resistance of a circuit element, which is usually useless information.
A: If the first voltmeter has (large, ideally infinite) resistance $R_1$ and the second voltmeter has (large, ideally infinite) resistance $R_2$ then the voltage across the first voltmeter would read
$$ \frac{R_1}{R_1 + R_2} E$$
and the second voltmeter would read
$$ \frac{R_2}{R_1 + R_2} E$$
Voltmeter's really measure current and are calibrated to read volts if the resistance of the meter is known $( V = I \times R)$.
The sum of the voltmeter readings would be $E$. If the voltmeters were identical each would read $E/2$.
A: A voltmeter reads the voltage drop across it.
Normally, voltmeters are connected in parallel to other circuit elements.  Since all elements connected in parallel have the same voltage drop, the reading on the voltmeter is the same as the voltage drop across the other elements.
Adding a new element changes the circuit, which changes the current through and voltage drop across the other elements.  To minimize this effect, a voltmeter's resistance should be large compared to the other elements in the circuit.  This way it will draw very little current.  A voltmeter is a big resistor.
What happens when you connect two large resistors to a battery like that?  Are the voltmeters identical?  You can use Kirchhoff's laws to determine the voltage drop across and current through each.
