As shown in the figure, a block is placed in front of a convex lens. Choose the most appropriate image of the block from the following options:
Step 1: The image formation by a convex lens depends on the object's position relative to the focal point and the lens. - If the object is placed between the focus and the lens, the image formed will be virtual, upright, and magnified.
- If the object is placed beyond twice the focal length, the image formed will be real, inverted, and diminished.
Step 2: In this case, the block is placed in front of the convex lens at a distance beyond \( 2F \) (twice the focal length), so the image formed will be real, inverted, and diminished.
Step 3: According to the given options, the image that fits the description of a real, inverted, and diminished image is Option 2.
Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): An electron in a certain region of uniform magnetic field is moving with constant velocity in a straight line path.
Reason (R): The magnetic field in that region is along the direction of velocity of the electron.
In the light of the above statements, choose the correct answer from the options given below:
