Question

Read the given statements carefully.
Statement-1: Every particle of matter exerts a special force to pull neighbouring particles towards itself.
Statement-2: When particles of matter come very close to each other, a repulsive force also starts operating along with attractive force and helps in retaining the identity of each particle.
Now, choose the correct option.

Both the statements are correct

Solution

The correct option is A Both the statements are correct
There exists a force of attraction between the particles of matter which hold them together. When the particles approach each other, a repulsive force also comes into play. Combination of attractive and the repulsive forces is responsible for maintaining the identity of each individual particle.
Hence, the correct answer is option (a).
