Answer:
option B
Explanation:
When you rub a clear plastic pen with the wool the plastic pen gets charges this phenomenon is known as frictional charging.
Due to rubbing, the pen gets negatively charged.
We know, opposite charge attract each other and the same charge repel each other.
So, when the pen is negatively charged the tape might be positively charged or the tape might be uncharged.
Hence, the correct answer is option B
Answer:
The “terminal speed” of the ball bearing is 5.609 m/s
Explanation:
Radius of the steel ball R = 2.40 mm
Viscosity of honey η = 6.0 Pa/s



While calculating the terminal speed in liquids where density is high the stokes law is used for viscous force and buoyant force is taken into consideration for effective weight of the object. So the expression for terminal speed (Vt)

Substitute the given values to find "terminal speed"




The “terminal speed” of the ball bearing is 5.609 m/s
