A person of mass 62 kg is inside of a lift of mass 940 kg and presses the button on control panel. The lift starts moving upwards with an acceleration 1.0 m/s2. If g = 10 m/s2 ,the tension in the supporting cable is

• 9680 N

• 11000 N

• 1200 N

• 8600 N

B.

11000 N

Total mass = Mass of lift + Mass of person

= 940 +60 = 1000 kg

T - mg = ma

Hence, T - 1000 x 10 = 1000 x 1
T = 11000 N

Total mass = Mass of lift + Mass of person

= 940 +60 = 1000 kg

T - mg = ma

Hence, T - 1000 x 10 = 1000 x 1
T = 11000 N

When the branches of an apple tree are shaken, the apples fall down. Why?

The apple fall from an apple tree when it shaken because of inertia of rest. Apple is in a state of rest and when the tree is suddenly shaken, apples still tends to remain in it's same state of rest whereas branches move.

So, the apples fall down.
