Display most popular posts of category

Right now in my slider I'm showing most popular post by views. However, I want to shop most popular post by views only for a certain category? The category id I want to use is "10". How would I achieve this? Thanks in advance.

div id="slider-food" 
?php 
$carousel_cat = get_theme_mod('carousel_setting','1'); 
$carousel_count = get_theme_mod('count_setting','4'); 
$month = date('m'); 
$year = date('Y'); 
$new_query = new WP_Query( array('posts_per_page' = $carousel_count, 'meta_key' = 'wpb_post_views_count', 'orderby' = 'meta_value_num', 'order' = 'DESC','monthnum'=$month,'year'=$year )); 
? 
?php if ( $new_query-have_posts() ) : ? 
?php while ( $new_query-have_posts() ) : $new_query-the_post(); ? 
div class="item" 
    ?php the_post_thumbnail('popular-posts'); ?
    h2a class="popular-category" 
        ?php 
        $categories = get_the_category(); 
        $separator = ", ";
        $output = '';

        if ($categories) {
            foreach ($categories as $category) {
                $output .= 'a href="' . get_category_link($category-term_id) . '"' . $category-cat_name . '/a' . $separator;
            }
            echo trim($output, $separator);
        }

        ?/a/h2
 p
     a class="popular-excerpt" href="?php the_permalink(); ?"?php echo get_the_excerpt(); ?/a
                /p
/div 
?php endwhile; wp_reset_postdata(); ? 
?php else : ? 
p?php _e( 'Sorry, No Popular Posts Found ' ); ?/p 
?php endif; ? 
/div
