Question 253: Laws of Motion

Question

A lift of mass 1000 kg which is moving with acceleration of 1 m/s2 in upward direction, then the tension developed in string which is connected to lift is

Accepted Answer

For a lift which is moving in upward direction
with an acceleration a, the tension T developed in
the string connected to the lift is given by
T = m (g + a).
Here m = 1000 kg, a = 1 m/s
2
, g = 9.8 m/s
2
$$ 	herefore $$ T = 1000(9.8 + 1) = 10,800 N.

Answer

9800 N

Answer

10,800 N

Answer

11,000 N

Answer
