AIPMT PRELIMS 2002 Physics Tension in Strings MCQ Question
Type: MCQ-numerical-Medium-Class 11
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
11000 N
D
10, 000 N
Correct Answer
Option B
Detailed Explanation
The tension in the string is calculated using T = m(g + a), where m = 1000 kg, g = 9.8 m/s², and a = 1 m/s². Thus, T = 1000(9.8 + 1) = 10800 N.
