Q. If the angle of incidence is equal to the critical angle, what is the behavior of the light ray?
A.
It is refracted at 90°.
B.
It is totally internally reflected.
C.
It is absorbed.
D.
It is transmitted.
Solution
When the angle of incidence equals the critical angle, the light ray is refracted along the boundary at 90°, marking the threshold for total internal reflection.
Q. If the angle of inclination of a plane increases, what happens to the static friction force acting on an object resting on the plane?
A.
Increases
B.
Decreases
C.
Remains constant
D.
Becomes zero
Solution
As the angle increases, the component of gravitational force parallel to the plane increases, which can lead to a decrease in static friction until it reaches its maximum value.
Q. If the angle of inclination of a plane increases, what happens to the static frictional force acting on an object resting on the plane?
A.
Increases
B.
Decreases
C.
Remains constant
D.
Becomes zero
Solution
As the angle increases, the component of gravitational force parallel to the plane increases, which can lead to a decrease in static friction until it reaches its maximum value.
Q. If the angles of a quadrilateral are in the ratio 1:2:3:4, what is the measure of the largest angle?
A.
90 degrees
B.
120 degrees
C.
150 degrees
D.
180 degrees
Solution
Let the angles be x, 2x, 3x, and 4x. The sum of angles in a quadrilateral is 360 degrees. Therefore, x + 2x + 3x + 4x = 360, which gives 10x = 360, so x = 36 degrees. The largest angle = 4x = 144 degrees.
Q. If the angles of a triangle are in the ratio 2:3:4, what is the measure of the largest angle?
A.
60 degrees
B.
80 degrees
C.
90 degrees
D.
120 degrees
Solution
Let the angles be 2x, 3x, and 4x. The sum of angles in a triangle is 180 degrees. Therefore, 2x + 3x + 4x = 180. Solving gives x = 20, so the largest angle is 4x = 80 degrees.
Q. If the area of a coil is doubled while keeping the magnetic field constant, what happens to the magnetic flux through the coil? (2023)
A.
It doubles
B.
It halves
C.
It remains the same
D.
It quadruples
Solution
Magnetic flux (Φ) is given by the product of magnetic field (B) and area (A). If the area is doubled and the magnetic field remains constant, the magnetic flux also doubles.
Q. If the area of a loop in a magnetic field is doubled while keeping the magnetic field strength constant, what happens to the magnetic flux through the loop?
A.
It doubles
B.
It halves
C.
It remains the same
D.
It quadruples
Solution
Magnetic flux (Φ) is given by Φ = B * A. If the area (A) is doubled and the magnetic field (B) remains constant, the magnetic flux also doubles.
