These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses
Assertion Block A is resting on one corner of a box as shown in figure. Acceleration of box is `(2hati+2 hatj)ms^(-2)`. Let `N_(1)` is the normal reaction on block from vertical wall and `N_(2)` from ground of box. Then `(N_(1))/(N_(2))=(1)/(6)`.(Neglect friction)
Reason `N_(1)=0`, if lift is stationary.

A

If both Assertion and reason are true and the reason is a correct explanation of the assertion.

B

If both Assertion and reason are true and the reason is not the correct explanation of the assertion.

C

if assertion is true but reason is false

D

if assertion is false but reason is true

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `N_(1)=ma_(x)=2m`
`N_(2)=m(g+a_(y))=12m`
`therefore" " (N_(1))/(N_(2))=(1)/(6)`
