Answer:
tyre pressure monitoring system (TPMS)
Explanation:
It very important to inflate your tyres to the specified pressure. So cultivate a habit to check and refill them once a month. Note that you can't tell if a tyre is underinflated just by looking at it. If it actually looks underinflated in a way. And you can't really rely on a tyre pressure monitoring system (TPMS) only to keep track. Most systems only warn you when the pressure is 25 percent below the manufacturer's recommended tyre pressure.
Answer:
Explanation:
Force on Q₃ due to charge Q₁
= 9 x 10⁹x 4 x 10⁻⁹ x1 x 10⁻⁹ / 5²
= 1.44 x 10⁻⁹ N
Force due to Q₂ will also be 1.44 x 10⁻⁹ N
component of these forces along x axis
-= 2 x 1.44 x 10⁻⁹ cosθ
= 2.88 x 10⁻⁹ x 4/5
= 2.30x10⁻⁹ N along x axis.
The y-component will calcel out.
b ) In this case , Q₁ will repel and Q₂ will attract.
In this case Q₁ will repel and Q₂ will attract. Component along y - axis will be same as earlier one or 2.30x10⁻⁹ N . Component along x axis will cancel out.
c ) Electric field in case 1 and case 2 will be
= 2.30x10⁻⁹ / 1 x 10⁻⁹
= 2.3 N / C , because field is force per unit charge. The sane field will be in case 2 .
