Question

11. A block of mass m is resting inside a smooth horizontal tube. If the tube accelerates vertic
downward obeying the relation a = kt, where K is a positive constant and 't' is instant of time.
normal reaction as a function of time and plot N Vs t curve and NVt.
m
1
1) N = kt + mg
* N = kt - mg
3) N = mg – k/t
4) N = m/gkt​

Answer 1

Answe

3) N = mg – k/t

Explanation:

A block of mass m is resting inside a smooth horizontal tube. If the tube. If the tube accelerates vertically downward obeying the reaction a = kt, where K is a positive constant and 't' is instant of time. Find normal reaction as a function of time and plot N Vs t curve and ∣N∣v

Answer 2

Answer:

mg-n=ma

mg-n=mkg

n=mg-mkt
