Correct answer: Option D. 30 V

The resistors are connect in series, because in parallel the potential drop across all resistors will have been the same and will be equal to the battery voltage i.e. 60 V.

First we need to find the equivalent resistance and the current passing through the circuit.

Since, resistors are in series, equivalent resistance will be the sum of all individual resistances. So,

Equivalent Resistance = 20 + 40 + 60 = 120 ohm
Current through the circuit = Voltage / Equivalent Resistance  = 60/120 = 0.5 ampere

The voltage drop across R3 =Resistance of R3 x Current 
= 60 x 0.5
= 30 V

Therefore, D option is the correct answer.

Here is a force diagram of an object in water. The weight of the object is 15N and the buoyancy force is 17N. Will the object fl
lawyer [7]

Answer:

Object will float.

Explanation:

Total force on the body = Weight of body + Buoyancy force on body.

 Weight of body = 15 N downwards = 15 N

 Buoyancy force on body = 17 N upwards = -17 N

 Total force on body = 15 - 17 = -2 N = 2 N upwards

 So, the body will float.

Object will float.
