Q. If the difference between the compound interest and simple interest on a certain sum of money for 2 years at 10% per annum is $50, what is the principal? (2000)
A.
$1000
B.
$1200
C.
$1500
D.
$2000
Solution
The difference between compound interest and simple interest for 2 years is given by SI * (r/100)^2. Setting this equal to $50 and solving gives Principal = $1200.
Q. If the difference between the compound interest and simple interest on a sum of money for 2 years at 10% per annum is $50, what is the principal? (2000)
A.
$1000
B.
$1200
C.
$1500
D.
$2000
Solution
The difference SI and CI for 2 years is given by P * r^2 / 200. Setting this equal to 50 gives P = $1500.
Q. If the distance between two charges is doubled, how does the force between them change?
A.
It doubles
B.
It halves
C.
It quadruples
D.
It reduces to one-fourth
Solution
According to Coulomb's law, force is inversely proportional to the square of the distance. If the distance is doubled, the force reduces to one-fourth.
Q. If the distance between two charges is halved, how does the force between them change?
A.
It doubles
B.
It quadruples
C.
It remains the same
D.
It halves
Solution
According to Coulomb's law, the force F between two charges is inversely proportional to the square of the distance. If the distance is halved, the force becomes four times greater.
Q. If the distance between two point charges is tripled, how does the electrostatic force between them change? (2020)
A.
It triples
B.
It halves
C.
It becomes one-ninth
D.
It remains the same
Solution
According to Coulomb's law, the force F is inversely proportional to the square of the distance (F ∝ 1/r^2). If r is tripled, F becomes 1/9 of its original value.
Q. If the distance from the center of the Earth is doubled, what happens to the gravitational field strength?
A.
It doubles.
B.
It halves.
C.
It becomes one-fourth.
D.
It becomes zero.
Solution
The gravitational field strength varies inversely with the square of the distance from the center of the Earth, so if the distance is doubled, the field strength becomes one-fourth.
Q. If the Earth were to suddenly shrink to half its radius while keeping its mass constant, what would happen to the gravitational force at its surface?
A.
It would remain the same
B.
It would double
C.
It would become half
D.
It would become four times stronger
Solution
If the radius is halved, the gravitational force increases by a factor of 4, since F = GM/R^2.
Correct Answer:
D
— It would become four times stronger
