A stretching force of 1 N is applied at one end of a spring balance and an equal sretching force is applied at the other end at the same time. The reading on the balance will be

If two ends of a spring balance are pulled each by a force of 10 kg. wt. What will be the reading of the balance?

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 endsfree 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 endsfree 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 ?

A spring is strecthed by applying a load to its free end. The strain produced in the spring is

Why do spring balances show wrong readings after they have been used for a long time?

Oif a force 20 N is applied on a body of mass 5 kg at rest then find the kinetic energy of the body after 10s.

A copper and a steel wire of the same diameter are connected end to end. A deforming force F is applied to this composite wire which causes a total elongation of 1 cm. The two wies will have

Action and reaction forces do not balance each other. Why?
