Question : 7 of 51

Marks: +1, -0

A positive, singly ionized atom of mass number AM is accelerated from rest by the voltage 192 V . Thereafter, it enters a rectangular region of width w with magnetic field

Tesla, as shown in the figure. The ion finally hits a detector at the distance x below its starting trajectory.
[Given: Mass of neutron/proton =(5∕3)×10−27‌kg , charge of the electron =1.6×10−19C .]

Which of the following option(s) is(are) correct

[JEE Adv 2024 P2]

The value of x for H+ion is 4 cm .
The value of x for an ion with AM=144 is 48 cm .
For detecting ions with 1≤AM≤196, the minimum height (x1−x0) of the detector is 55 cm .
The minimum width w of the region of the magnetic field for detecting ions with AM=196 is 56 cm .
