5.0 Ω
0.5 Ω
10.0 Ω
1.0 Ω
Correct answer is D
since resistance R = p (l)/a
= (4 x 10-7 x 20)/8.0 x 10-6
R = 1.0 Ω
the charge must be of opposite sign
positive charges are more in number
the charges are electrically neutral
the charges are of the same sign
Correct answer is A
The charge must be opposite in sign, since the positive charges will deflect to the negative plate, and the negative charge to the positive plate
The electric field intensity in a place where a charge of 10-10c experiences a force of 0.4N is?
4.0 x 107 NC-1
8.0 x 109 NC-1
8.O x 10-12 NC-1
4.0 x 109 NC-1
Correct answer is D
The electric force experienced in an electric field of intensity E is given by:
F = qE: where q = the test charge.
E = F/Q = 0.4/10-10 = 0.4 X 10-10
= 4.0 X 109 NC-1
10 hrs
18 hrs
20 hrs
25 hrs
Correct answer is B
For a car battery rated 45 AH, being charged by a charger of 2.5 A rating, the time for the battery to be fully charged is given by:
T = (45)/2.5 = 18 hrs
