When a force F is applied to the combination of springs, the forces F1 and F2 applied on individual springs are given by<br />F1 = k1x and <br />F2 = k2x where x is the extension.<br />The applied force F is the sum of the above forces. Therefore we have<br />F = keq x = F1 + F2 where keq is the effective spring constant of the combination.<br />Therefore, keq x = k1x + k2x<br />This gives keq = k1 + k2<br />If there are n springs we have<br />keq = k1 + k2 + k3 +……. kn<br />In the present case we have 3 identical springs each of spring constant 3k,<br />Therefore keq = 3k + 3k +3k =9k<br />MVhttps://www.blogger.com/profile/05910408858112321196noreply@blogger.comtag:blogger.com,1999:blog-32436271.post-50221737255137043822020-12-31T09:21:55.042+05:302020-12-31T09:21:55.042+05:30sir I did not understand the last question when th...sir I did not understand the last question when the springs are in parallel shouldnt the equivalent spring constant be k/3?<br /><br />Anonymoushttps://www.blogger.com/profile/00457469056815703862noreply@blogger.com
