Weekly Quiz Competition

Question 1
1 / -0

Which of the following does not contain material particles

A
Alpha rays

B
Beta rays

C
Gamma rays

D
Canal rays

Solution

y - rays does not contain material particles.
Question 2
1 / -0

Radioactive substances emit g-rays, which are

A
+ ve charged particle

B
– ve charged particle

C
Massive particle

D
Packet of energy

Solution

y - rays are neutral energy packet.
Question 3
1 / -0

Which statement is incorrect

A
α -rays have more penetrating power than β -rays

B
α -rays have less penetrating power than γ -rays

C
β -rays have less penetrating power than γ -rays

D
β -rays have more penetrating power than α -rays

Solution

The order of penetrating power is : α < β < γ-rays. It is due to lower mass and high speed.
Question 4
1 / -0

The radiations having high penetrating power and not affected by electrical and magnetic field are

A
Alpha rays

B
Beta rays

C
Gamma rays

D
Neutrons

Solution

γ-rays have maximum penetrating power.
Question 5
1 / -0

α-particles can be detected using

A
Thin aluminum sheet

B
Barium sulphate

C
Zinc sulphide screen

D
Gold foil

Solution

Rutherford first of all used zinc sulphide (ZnS) as phosphor in the detection of α-particles.
Question 6
1 / -0

Alpha rays consist of a stream of

A
H⁺

B
He⁺²

C
Only electrons

D
Only neutrons

Solution

α-rays consist of a stream of He⁺².
Question 7
1 / -0

Which is the correct statement

A
Isotopes are always radioactive

B
β -rays are always negatively charged particles

C
α -rays are always negatively charged particles

D
γ -rays can be deflected in magnetic field

Solution

α-rays are positively charged, β-rays are negatively charged, γ-rays carry no charge and thus not deflected in field.
