Answer: what are the answers?
Explanation:
Answer:
Option d) can not be determined from the given information
Explanation:
Water is a polar molecule consisting of 2 positive hydrogen atoms and a negative oxygen atom.
When a stream of water is deflected by positively charged object, the water molecules are oriented in such a way that oxygen in water, being negatively charge gets attracted to the charged object and aligns near the object whereas hydrogen aligns on the opposite side overcoming the inter-atomic repulsion.
Similar is the case with hydrogen in case the object is negatively charged.
Therefore, it explains that water is a polar molecule and gets attracted to both positive and negative charges and hence, the sign of the object can not be determined.
Answer:
200 C
Explanation:
Let C1 and C2 be their charges. According to Coulomb's law
where k = 
is the constant, R = 0.4m is the distance between them, F = 120 N is their resulting charge force
Since their total charge is 200C:
or 
We can substitute the above equation
or 
So the larger charge is C = 200 C
