Question

Instruction : Question No. 1(B) is fill in the blanks type. Each question carry 1 mark. प्र.1 (i) । Simple Harmonic Motion is based on conservation of .... (ii) The focal length of plane mirror is .... ​

Answer 1

1. Simple Harmonic Motion is based on conservation of TOTAL MECHANICAL ENERGY

2. The focal length of plane mirror is INFINITY

Detailed discussion:

1. In SHM, the force parameter is dependent on displacement as follows:

$F \propto - x$

• Now, PE of object = ½mw²x²
• KE of object = ½mw²(A² - x²)

But total energy :

• TE = ½mw²A² is a constant.

2. Plane mirror has infinite Radius of Curvature, because it can be considered as a sphere with infinite Radius.

Hope It Helps.

Answer 2

Answer:

1. Simple Harmonic Motion is based on conservation of TOTAL MECHANICAL ENERGY

2. The focal length of plane mirror is INFINITY

Detailed discussion:

1. In SHM, the force parameter is dependent on displacement as follows:

F \propto - xF∝−x

Now, PE of object = ½mw²x²

KE of object = ½mw²(A² - x²)

But total energy :

TE = ½mw²A² is a constant.

2. Plane mirror has infinite Radius of Curvature, because it can be considered as a sphere with infinite Radius.
