Why does a passenger feel lighter when the lift is about to stop at a higher floor during its upward motion?

Correct Answer - `198.77` MeV

1. Newton’s first law shows an equivalence between the ‘state of rest’ and ‘state of uniform motion along a straight line.’ 2. Newton’s first law of motion defines force as a physical...

No. In projectile motion, the horizontal and vertical motion are independent of each other because both motions don’t affect each other.

1. The lift is said to be moving with net upward acceleration in two possible conditions: when the lift just starts moving upwards or is about to stop at a lower floor...

If the cables of the lift are cut, the downward acceleration of the lift, ad = g. In this case, we get, N = mg – mad = 0

i. True  ii. False, In Rutherford’s experiment of scattering of α-particles by thin gold foil, very few α-particles bounced back. iii. False,  Cathode rays are a stream of very small, negatively charged particles.

Possible reasons for the upward bending at the road could be: i. Angle of incidence at the road is glancing. At glancing incidence, the reflection coefficient is very large which causes...

A) accelerated

B) Centrifuge

Correct option is C) 5 m
