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 :- (A) 9800 N (B) 10,800 N (C) 11,000 N (D) 10,000 N

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 k g, a = 1 m / s^{2}, g = 9.8 m / s^{2}

∴ T = 1000 (9.8 + 1) = 10, 800 N

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

9800 N

10,800 N

11,000 N

10,000 N

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=1000kg,a=1m/s2,g=9.8m/s2 ∴T=1000(9.8+1)=10,800N

Q. A lift of mass $1000 k g$ which is moving with acceleration of $1 m / s^{2}$ in upward direction, then the tension developed in string which is connected to lift is :-

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 $m = 1000 k g, a = 1 m / s^{2}, g = 9.8 m / s^{2}$
$∴ T = 1000 (9.8 + 1) = 10, 800 N$
