QAIPMT-2011-Ph-1921: NEET 2011 Physics - Class 11 AIPMT-2011-Ph-1921 Solution: A uniform electric field and a uniform magnetic field are…
A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the region such that its velocity is pointed along the direction of fields then the electron will turn towards right of direction of motion speed will decrease speed will increase will turn towards left of direction of motion

Step-by-Step Verified Solution
Here, Mass of a person, m = 60 kg
Mass of lift, M = 940 kg,
a = 1 m/s 2 , g = 10 m/s 2
Let T be the tension in the supporting cable.
_ T � (M + m)g = (M + m)a
_ T = (M + m)(a + g)= (940 + 60)(1 + 10) = 11000 N
