Question

Qn11. A spring balance is attached to the ceiling of a stationary lift. A man suspends a block from the hook of
the spring balance and balance reads 98N. What will be reading of spring balance, if the lift starts moving
downward with the acceleration of 2m/s??
Qn12. During the explosion, a bomb explodes into three pieces. Two fragments whose masses are 0.8kg and​

Answer 1

Answer:

now Reading of a string is acceleration on body is equal to m(g-a)

Explanation:

=

Answer 2

Answer:

Explanation:

The reading in the spring balance will decrease and will show a value less than 98N as the acceleration of the lift will add with the gravitation (g) which will reduce the force exerted by the mass on the spring balance .......
