From this nice answer with some modifying.

\documentclass[a4paper,addpoints]{exam}

\makeatletter
\@qformatfalse
\def\droppointsatend{%
  \def\level@of@question{question}%
  \leavevmode\unskip\nobreak%
  \ifx\level@of@question\@queslevel%
    \dotfill(\mbox{\totalpoints\ \points})%
  \else%
    \quad \mbox{(\@points\  \points)}%
  \fi%
  \par
}
\makeatother

\begin{document}
\pointsdroppedatright
\begin{questions}
\question Some questions about emotions. 
    \begin{parts}
        \part[2] Are we happy? \droppointsatend
        \part[2] Are we mad? \droppointsatend
        \part[2] Are we mad Are we mad Are we mad Are we mad Are we mad Are we mad Are we mad Are we mad Are we mad Are we mad? \droppointsatend
    \end{parts}  

\question Second questions about emotions.   
\begin{parts}
        \part[2] Are we happy? \droppointsatend
        \part[2] Are we mad? \droppointsatend 
 \end{parts}    
\end{questions}


\noindent Total to earn: \numpoints\ \points


\end{document}

Answer 2

You can try the following code. This should give the desired result:

\documentclass[11pt]{exam}
\begin{document} 
\begin{questions} 
\question Some questions about emotions. 
    \begin{parts}
        \part Are we happy? (2 points)
        \part Are we mad? (2 points)
    \end{parts}    
\end{questions}
\end{document}
