The tension is the spring is

A

zero

B

2.5 N

C

5 N

D

10 N

Text Solution

Verified by Experts

The correct Answer is:
C

5N force will not produce any tension in spring without support of othr 5 N force. So here the tension in the spring will be 5 N only.

The tension in the spring is.

A smooth table is placed horizontally and a spring of unstretched length i_(0) and force constank k has one end fixed to its center. To the other end of the spring is attached a mass m which is making n revolutions per second around the center. Show that the radius r of this unifrom circular motion is kl_(0)//(k-4 pi^(2)mn^(2)) and the tension T in the spring is 4pi^(2)mkl_(0)n^(2)//(k-4pi^(2)mn^(2))

A body of mass m= 20 g is attached to an elastic spring of length L=50 cm and spring constant k=2 Nm^(-1) . The syste is revolved in a horizontal plan with a frequency v=30 rev/min. Find the radius of the circular motion and the tension in the spring .

In an elevator a system is arranged as shown in figure. Initially elevator is at rest and the system is in equilibrium with middle spring unstretched. When the elevator accelerated upwards, it was found that for the new equilibrium position (with respect to lift), the further extension i the top spring is 1.5 times that of the further compression in the bottom spring, irrespective of the value of acceleration (a) Find the value of (m_1)/(m_2) in terms of spring constants for this happen. (b) if k_1=k_2=k_3=500(N)/(m) and m_1=2 kg and acceleration of the elevator is 2.5(m)/(s^2) , find the tension in the middle spring in the final equilibrium with respect to lift.

A spring of force constant k extends by a length X on loading . If T is the tension in the spring then the energy stored in the spring is

In the system shown in fig. m_(1) gt m_(2) . The system is held at rest by thread BC. Now thread BC is burnt. Answer the following: Just after burning the thread, what is the tension in the spring?

Figure shows a light spring balance connected to two blocks of mass 20 kg each. The graduations in the balance measure the tension in the spring. A. What is the reading of the balance? b.Will the reading change if the balance is heavy, say 2.0 kg? c. What will hapen if the spring is light but the blocks the unequal masses?

Assertion : Two identical balls are charged by q. They are suspended from a common point by two insulating threads l each. In equilibrium, the angle between the tension in the threads is 180^(@) . (Ignore gravity). Reason : In equilibrium tension in the spring is T=1/(4pi epsi_(0)) (q.q)/l^(2)
