A simple pendulum with a period of 2.0s has its length doubled. Its new period is
1.00s
1.41s
0.3s
2.83s
4.00s
Correct answer is D
Using \(\frac{T_1}{T_2}\) = \(\sqrt\frac{L_1}{L_2}\)
\(\frac{2}{T_2}\) = \(\sqrt\frac{L_1}{2L_1}\)
T2 = 2.83sec
Which of the following is most strongly deflected by magnetic field?
\(\gamma\) - rays

1.3 x 1015Hz
7.5 x 105Hz
1.2 x 1011Hz
7.5 x 1014Hz
Correct answer is D
F = \(\frac{V}{\lambda}\)
= \(\frac{3 \times 10^8}{400 \times 10^{-9}}\)
= 75 x 1015Hz
= 7.5 x 10^14 Hz
