(i) and (ii).<\/p>\n<p>When the tank is decelerated, the ball and the bubble will both experience a force in the opposite direction of the motion of the tank. This force is called inertia. The ball has a greater mass than the bubble, so it will experience a greater force of inertia. This means that the ball will move to the front of the tank, while the bubble will move to the rear of the tank.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li>Option (i): The ball will move to the front. This is because the ball has a greater mass than the bubble, so it will experience a greater force of inertia. This force will cause the ball to move in the opposite direction of the motion of the tank, which is to the front.<\/li>\n<li>Option (ii): The bubble will move to the rear. This is because the bubble has a smaller mass than the ball, so it will experience a smaller force of inertia. This force will cause the bubble to move in the opposite direction of the motion of the tank, which is to the rear.<\/li>\n<li>Option (iii): The ball will move to the rear. This is incorrect because the ball has a greater mass than the bubble, so it will experience a greater force of inertia. This force will cause the ball to move in the opposite direction of the motion of the tank, which is to the front.<\/li>\n<li>Option (iv): The bubble will move to the front. This is incorrect because the bubble has a smaller mass than the ball, so it will experience a smaller force of inertia. This force will cause the bubble to move in the opposite direction of the motion of the tank, which is to the rear.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;(i) and (ii)&#8221; option2=&#8221;(i) and (iv)&#8221; option3=&#8221;(ii) and (iii)&#8221; option4=&#8221;(iii) and (iv)&#8221; correct=&#8221;option1&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[648],"tags":[],"class_list":["post-7282","post","type-post","status-publish","format-standard","hentry","category-hydraulics-and-fluid-mechanics","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>A closed tank containing water is moving in a horizontal direction along a straight line at a constant speed.
