The acceleration of `10 kg` block on the inclined plane is

A

zero

B

`4 m//s^(2)`

C

`6 m//s^(2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

`10 xx 10 xx 1//2`
`100 - 2T = 10a` …(i)
`T - 50 = 10 xx 20` …(ii)
Multiplying (2) with 2 and adding (1) to it
`100 - 2T = 10a`
`2T - 100 = 40a "________"`
`a = 0`
