Answer:
15.32°
Explanation:
We have given the wavelength
Diffraction grating is 1460 lines per cm
So (as 1 m=100 cm )
For maximum diffraction
here m is order of diffraction
So
Answer:
The magnitude of the applied torque is
(e) is correct option.
Explanation:
Given that,
Mass of object = 3 kg
Radius of gyration = 0.2 m
Angular acceleration = 0.5 rad/s²
We need to calculate the applied torque
Using formula of torque
Here, I = mk²
Put the value into the formula
Hence, The magnitude of the applied torque is
