10 cm লম্বা ও 0.5 cm ব্যাসার্ধ বিশিষ্ট একটি তামা ও একটি লোহার তারকে জোড়া লাগিয়ে দৈর্ঘ্য 20 cm করা হল। জোড়া লাগানো তারটিকে বল প্রয়োগ করে লম্বা করা হল। লোহার ইয়ংয়ের গুণাঙ্ক তামার ইয়ংয়ের গুণাঙ্কের দুইগুণ হলে লোহার দৈর্ঘ্য বৃদ্ধি ও তামার দৈর্ঘ্য বৃদ্ধির অনুপাত কত? ( A steel and a brass wire, both having 10 cm length and 0.5 cm radius, are joined together making the total length of the combined wire 20 cm. The combined wire is stretched by applying a force. If the Young's modulus of steel is twice as much as that of brass, what will be the ratio of the extension of steel to the extension of brass?)
