Q. In the context of physics, which of the following statements are correct with reference to the concept of ‘Force’?
1.A force-carrier is any species of particle that mediates the interactions between particles that experience that force.
2. Force is an agent that induces an object to change its velocity.
3.The stronger the force, the faster an object will move.
4.Weak force is responsible for certain kinds of radioactive decay
. Select the correct answer using the codes given below:
Explanation –
Statements 1, 2 and 4 are correct. Force-carriers are the particles that “carry” forces between other particles. Examples include photons (which carry the electromagnetic force), gluons (which carry the strong nuclear force), and W and Z bosons (which carry the weak nuclear force).
Force causes objects to accelerate, which means their velocity (speed and direction) changes.
Weak force is responsible for certain types of radioactive decay, like beta decay and neutrino emission. Weak force is one of the four fundamental forces in nature, along with the strong force, the electromagnetic force, and gravity.
Statement 3 is incorrect. While a stronger force can cause an object to accelerate more rapidly, the actual speed depends on both the force and the object’s mass. Newton’s second law of motion provides the relationship: force equals mass times acceleration.
