Two bodies of masses M and m(M>m) are allowed to fall from the same height. If
1 answer:
- Two bodies of masses M and m (M>m) are allowed to fall from the same height . If the air resistance for each be the same then both the bodies will reach the earth simultaneously .
- For same air resistance, acceleration of both the bodies will be same .
[A] If both assertion and reason are true and reason is the correct explanation of assertion .
[B] If both assertion and reason are true but reason is not the correct explanation of assertion .
[C] If assertion is true but reason is false
[D] If both assertion and reason are false
✍️ The force acting on the body of mass M are [its weight] ‘<u>Mg</u>’
- Mg are acting vertically downwards
- And air resistance F acting vertically upward .
Hence,
⚡ Now, M > m therefore, the body with larger mass will have greater acceleration and it will reach the ground first .

Answer:
wavelength = 437.27 nm
Explanation:
given data
first bright fringe = 2.96 mm
slit separation = 0.325 mm
distance D = 2.20 m
solution
we know that this is double slit experiment
so we apply here Fringe width formula that is
β = ....................1
is Wavelength of light and D is Distance between screen and slit and d is slit width
so put here value and we get
=
= 437.27 ×
m
wavelength = 437.27 nm
