Question 1963

Which of the following statements is correct ?

AProtons are negatively charged and are present in the nucleus

BElectrons are positively charged and are present in the nucleus

CElectrons are negatively charged and are present in the orbits

DThe entire mass of atom is distributed in the orbits.

Show answer

C. Electrons are negatively charged and are present in the orbitsExplanation: Electrons are negatively charged particles that revolve around the nucleus in fixed paths called orbits or shells. The nucleus contains positively charged protons and neutral neutrons, and most of the atom’s mass is concentrated in the nucleus.

Question 1962

The physical quantity which is measured as Kg m/s2 is:

AWork

BPower

CForce

DMotion

Show answer

C. ForceThe physical quantity measured in kg·m/s2 is Force. The SI unit of force is the Newton (N), which is defined as the force required to accelerate a mass of 1 kilogram by 1 meter per second squared. Mathematically, Force = Mass × Acceleration. Work: Measured in joules (N·m).Power: Measured in watts (J/s).Motion: Describes movement, not a measurable quantity in these units.

The brain of any computer system is:

AALU

DCPU

Show answer

D. CPUThe CPU (Central Processing Unit) is known as the brain of the computer. It performs all major operations such as processing data, executing instructions, and controlling other components. The CPU consists of two main parts — the Arithmetic Logic Unit (ALU) for calculations and the Control Unit (CU) for directing operations. ALU: Handles arithmetic and logic operations only.Memory: Stores data and instructions, but doesn’t process them.Control Unit: Directs the flow of data but works as part of the CPU.
