1.0 x 104Vm-1
1.0 x 105Vm-1
1.5 x 105Vm-1
2.0 x 105Vm-1
Correct answer is A
E = \(\frac{v}{d} = \frac{10^3}{0.1}\)
= 10000
= 1.0 x 104Vm-1
1.59 x 10-14 N
2.80 x 10-7 N
1.30 x 10-2 N
6.30 x 1013 N
Correct answer is B
F = \(\frac{GM_1M_}{r^2}\)
= \(\6.67 \times 10^{-11} \times 70 \times 60}{1^2}\)
= 2.8014 x 10-7 N
The electricity meters in houses measure energy unit consumed in

8.0 x 102m
8.8 x 103m
8.0 x 104m
8.8 x 104m
Correct answer is B
R = \(\frac{4eL}{\pid^2}\)
L = \(\frac{R\pid^2}{4e}\)
= \(\frac{21 \times 3.14(4 \times 10^{-3})^2}{4 \times 3.0 x 10^{-8}}\)
= 8.8 x 103m
70.0
17.5
7.0
0.7
Correct answer is A
Magnify power = \(\frac{f_o}{f_e}\)
= \(\frac{3.5 \times 100}{5.0}\)
= 70
