A spring of force constant k is cut into length of ratio 1 : 2 : 3 . They are connected in series and the new force constant is k'. Then they are connected in parallel and force constant is k''. That k' : k'' = …………..
Four massless springs whose force constants are 2k, 2k, k and 2k respectively are attached to a mass M kept on a frictionless plane (as shown in figure). If the mass M is displaced in the horizontal direction.
Two springs of spring constant k_(1)" and "k_(2) are joined in series. Hence its equivalent spring constant of the combination is…………
Two spring of force constants k and 2k are connected to a mass as shown in figure. The frequency of oscillation of the mass is……..
Assertion:- A spring of force constatn k is cut in to two piece having lengths in the ratio 1:2 The force constant of series combination of the two parts is (3k)/(2) reason:- The spring connected in series are represented by k=k_(1)+k_(2)
A spring of force constant k is cut into two parts such that length of one part is double to another part. What will be the force constant of larger part?
Two springs of force constants k_(1) and k_(2) , are connected to a mass m as shown. The frequency of oscillation of the mass is f . If both k_(1) and k_(2) are made four times their original values, the frequency of oscillation becomes
Figure 14.26 (a) shows a spring of force constant k clamped rigidly at one end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure 14.26 (b) shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in Fig. 14.26(b) is stretched by the same force F. What is the maximum extension of the spring in the two cases ?
Figure 14.26 (a) shows a spring of force constant k clamped rigidly at one end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure 14.26 (b) shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in Fig. 14.26(b) is stretched by the same force F. If the mass in Fig. (a) and the two masses in Fig. (b) are released, what is the period of oscillation in each case ?
