XII Physics 2026 Assertion Reason 4 in 1

Assertion (A) : All atoms have a net magnetic moment Reason (R) :A current loop does not always behave as a magnetic dipole Assertion (A) : If accelerated electrons are passed through a narrow slit, a diffraction pattern is observed. Reason (R): Electrons behave as both particles and waves. Assertion (A) : The mass of a nucleus is less than the sum of the masses of the constituent nucleons. Reason (R): Energy is absorbed when the nucleons are bound together to form a nucleus. Assertion (A): In Bohr model of hydrogen atom, the energy levels are discrete and quantised Reason (R): In a hydrogen atom, the electrostatic force on the electron provides the necessary centripetal force to it to revolve around the nucleus. 12th Physics CBSE PYQ 2026 12th Physics CBSE PYQ 2025 CBSE 12th Physics Solution Class 12th CBSE Physics Class XII CBSE Physics CBSE 12th PYQ 2026 Physics CBSE 12th PYQ 2025 Physics CBSE 12th PYQ 2024 Physics CBSE with PYQ 2023 2025 2026 Physics 12th PYQ CBSE Solution Physics 12th CBSE sample paper solution Physics Class 12th CBSE Physics Previous year questions solution Class 12th CBSE Physics Previous year questions solution CBSE Maths 12th PYQ Solution Physics #cbseboard #cbse #cbseclass12 #maths #physics #study #boardexam #class12th #examination #education #science #physics
