State whether the following statements are true or false :-
(1) Magnitude of `vecP` can be -5 unit.
(2)`|hatN|=1`
(3) Magnitude of any vector is a scalar.
(4) Unit vectors of a vector cannot be zero.

Answer

To determine whether the given statements are true or false, let's analyze each statement one by one.

### Step 1: Analyze Statement (1)
**Statement:** Magnitude of `vecP` can be -5 unit.

**Solution:** The magnitude of any vector is always a non-negative quantity. Magnitudes cannot be negative because they represent the length or size of the vector. Therefore, the statement is **False**.

### Step 2: Analyze Statement (2)
**Statement:** `|hatN| = 1`

**Solution:** A unit vector, denoted as `hatN` (or `n cap`), is defined to have a magnitude of 1. Thus, the statement is **True**.

### Step 3: Analyze Statement (3)
**Statement:** Magnitude of any vector is a scalar.

**Solution:** The magnitude of a vector is indeed a scalar quantity because it only has size and no direction. Therefore, the statement is **True**.

### Step 4: Analyze Statement (4)
**Statement:** Unit vectors of a vector cannot be zero.

**Solution:** A unit vector is defined as a vector with a magnitude of 1. Since a unit vector cannot have a magnitude of 0, the statement is **True**.

### Summary of Answers:
1. False
2. True
3. True
4. True
