Question
As shown in the figure, two equal masses each of 2 kg are suspended from a spring balance. The reading of the spring balance will be
- Zero
- 2 kg
- 4 kg
- Between zero and 2 kg
The correct answer is: 2 kg
In this case, one 2 kg wt on the left will act as the support for the spring balance. Hence its reading will be 2 kg

A particle of mass m moving with velocity u makes an elastic one dimensional collision with a stationary particle of mass m. They are in contact for a very short time T. Their force of interaction increases from zero to F0 linearly in time T/2, and decreases linearly to zero in further time T/2. The magnitude of F0 is
