6. Which charge could not be found on an object? (1) -0.8times 10^-19C (3) +1.6times 10^-19C (2) -1.6times 10^-17C (4) +3.2times 10^-17C Proof: Explain your reasoning/show calculations.

Answer 1

The charge that cannot be found on an object is (1) \(-0.8 \times 10^{-19}\)C.

Answer 2

## Step1 The problem involves the principle of charge quantization, which states that the charge on an object is quantized. This means that the charge on an object is always an integer multiple of the elementary charge. ## Step2 The elementary charge, denoted as \(e\), is the smallest unit of charge that exists in nature. It is approximately equal to \(1.6 \times 10^{-19}\) Coulombs (C). ## Step3 Therefore, any charge on an object must be a multiple of this elementary charge. For example, \(+1.6 \times 10^{-19}\)C is a multiple of the elementary charge, and so is \(+3.2 \times 10^{-17}\)C. ## Step4 However, the charge \(-0.8 \times 10^{-19}\)C is not a multiple of the elementary charge. The negative sign indicates that the charge is negative, but the magnitude of the charge is not a multiple of the elementary charge.
