  3. (c) The image is virtual, inverted, formed at the focal point, and the same size as the object.
  4. (d) The image is virtual, erect, formed on the same side as the object, and larger than the object.
Answer & solution

Answer: (b) The image is real, inverted, formed between the focal point and twice the focal length, and smaller than the object.

Answer: Option 2 — Real, inverted, between F and 2F, smaller than object
For a convex lens, when the object is placedbeyond 2F, the image isreal, inverted, diminished, and formedbetween F and 2Fon the other side → Option 2. (This is the principle of a camera.)

  2. (b) + 1.5
  3. (c) - 2
  4. (d) - 1.5
Answer & solution

Answer: (c) - 2

Answer: Option 3 — −2
Lens formula 1/v − 1/u = 1/f, with u = −18, f = +12.
1/v = 1/12 + 1/(−18) = (3 − 2)/36 = 1/36 ⟹ v = +36 cm.
Magnification m = v/u = 36/(−18) =−2(real, inverted, magnified) → Option 3.

  2. (b) The acceleration becomes zero
  3. (c) The acceleration is halved
  4. (d) The acceleration is doubled
Answer & solution

Answer: (c) The acceleration is halved

Answer: Option 3 — The acceleration is halved
a = F/m (constant F). If massdoubles, a = F/(2m) =½of original → acceleration is halved → Option 3.

  1. (a) C₆H₁₀
  2. (b) C₆H₁₄
  3. (c) C₆H₆
  4. (d) C₆H₈
Answer & solution

Answer: (b) C₆H₁₄

Answer: Option 2 — C₆H₁₄
A ring (or unsaturation) reduces the number of H atoms. For anopen-chain saturatedcompound CₙH₂ₙ₊₂: C₆ → 2(6)+2 =C₆H₁₄(no ring). C₆H₆ (benzene), C₆H₁₀, C₆H₈ have rings/double bonds → Option 2 is the non-ring one.
