Each question contains statements given ...

Each question contains statements given in two Columns, which are to be a matched. Statements in Column-I are labelled as B A, B, C and D, whereas statements in Column-II C are labelled as p, q, r and s. Match the entries of D Column-I with appropriate entries in Column-II. Each entry in Column-I may have one or more than one correct option from Column-II. The answers to these questions have to be appropriately bubbled as illustrated in the given example, if the correct matches are `A to (q,r), B to (p,s), C to (r,s)` and `D to (q)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
`A to (p,q,r,s)`
Gamma rays are electromagnetic waves which have highest penetrating power and cause nuclear reactions.
`B to ( r)`
`gamma` rays also have penetrating power but less than gamma rays and can cause nuclear reactions.
`C to (q)`:
When a radioactive element emits `beta^(-)` rays, then the mass number of the element remains unchanged and only atomic number increases.
`D to (q)`
For a positron emission by a radioactive element, mass number remains same and atomic number of daughter nucleus decreases.
