I have used below query:

$args = array(
'post_type' => 'blogs',
'tax_query' => array(
    array(
    'taxonomy' => 'blog',
    'field' => 'term_id',
    'terms' => $backendEngineering->term_id
     )
  )
);
$responseData = new WP_Query( $args );
echo '<br/>';
print_r($responseData);
echo '<br/>';

It's working fine. But My requirement is to fetch only post name and post ID. Is this possible? If it is then how can we do it?

You can get using return fields https://codex.wordpress.org/Class_Reference/WP_Query#Return_Fields_Parameter

Updated argument is following.

$args = array(
'post_type' => 'blogs',
 'fields'=>'ids',
'tax_query' => array(
array(
'taxonomy' => 'blog',
'field' => 'term_id',
'terms' => $backendEngineering->term_id
 )
 )
);

But here no option to return the title. Hope it will help you.

just write a function to loop through the query results and get the data you need

function echo_post_title_and_id(){
   $args = array(
   'post_type' => 'blogs',
   'tax_query' => array(
       array(
       'taxonomy' => 'blog',
       'field' => 'term_id',
       'terms' => $backendEngineering->term_id
        )
     )
   );
   $responseData = new WP_Query( $args );

      if ( $responseData->have_posts() ) {
              while ( $$responseData->have_posts() ) {
                     $responseData->the_post();
                      echo get_the_title();
                      echo get_the_id();
             }
      }else {
           echo 'no posts found';
      }
       wp_reset_postdata();
}
