• IntegermediumCurrent electricitycombination of cells and maximum power theorem

  Two cells of emfs 1 V and 2 V and internal resistances 2 Ω and 1 Ω respectively are connected in series with an external resistance of 6 Ω, giving current I₁. The same cells are then connected in parallel with the same external resistance, giving current I₂. If I₁/I₂ = x/3, find x.

• MCQmediumMagnetic effect of currentmotion of charge particle in magnetic field

  Assertion (A): If O²⁻ and H⁺ ions enter perpendicular to the same magnetic field with equal momentum, the path of O²⁻ has a smaller radius of curvature than that of H⁺. Reason (R): A proton and an electron having the same momentum form paths of different radii in the same magnetic field because their masses are different. Choose the correct answer.

  Options

  • Option A

    A is true but R is false

  • Option B

    Both A and R are true but R is NOT the correct explanation of A

  • Option C

    Both A and R are true and R is the correct explanation of A

  • Option D

    A is false but R is true
