Sagot :
Given that,
Four wooden blocks with masses of 2 kg, 5 kg, 7 kg, and 9 kg are placed on a table.
To find,
The block will have the least inertia.
Solution,
Inertia is the measure of mass of a body. It is directly proportional to the mass of the body.
The body having more mass will have more inertia. Out of four masses 9 kg block will have more inertia and 2 kg block will have least inertia.
Hence, the correct option is (a) " The block with a mass of 2 kg "
The wooden block of mass 2kg will have the least inertia.
The inertia of an object:
The inertia of an object is defined as the property due to which an object continues in the existing state of rest or uniform motion in a straight line unless an external force is applied.
The inertia of an object is directly proportional to the mass of the object. Havier the object, it will be more resistant to any change in its state of motion or rest.
if we consider the same amount of force applied to all the wooden blocks of masses 2kg, 5kg, 7kg, and 9kg, it will be easiest to move the 2kg block and hardest to move the 9 kg block.
So, the block of mass 2kg has the least inertia while the block of mass 9kg has the maximum inertia among the given blocks.
