TS EAMCET 03 May 2019 Shift 2 Solved Paper

The following figure shows the required diagram
The expression to calculate the radius of a circular path is given by,
R=‌

√2m(KE)

qB

Here, KE=qV
Substitute the given values in the above expression.
R‌‌=‌

√2×1.6×10−27×1.6×10−19×500×103

1.6×10−19×0.1

‌‌=1m
Hence, from figure,
φ+∠ADC=π ............ (1)
Where,
φ‌‌=‌

arc

radius

‌‌=‌

10−2

1

‌‌=0.01rad
And
θ=π−∠ADC .......... (2)
From equations (1) and (2)
φ‌‌=θ
‌‌=0.01rad
