Two point charges of+2μCand+6μCrepel each other with a force of12N. If each is given an additional charge of−4μC, what will be the new force? View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Class 8, Class ...
The force of attraction or repulsion is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges. We know that two like charges repel one another and two unlike charges...
1. Understanding Charge Interaction: - Two similarly charged bodies (both positively charged or both negatively charged) typically repel each other due to the electrostatic force. This is described by Coulomb's law, which states that like charges repel and opposite charges attract. 2. Induction ...
Two charged particles exert an electrostatic force of 20n on each other. What will the magnitude of the electrostatic force be if the distance between the charges is reduced to one-third of the original distance? What is the magnitude of electric field stren...
In many salt-rejecting membranes, positive surface charges are introduced via coatings or functional groups to repel cations [63,64]. This strategy can also be applied to improve Li+/Mg2+selectivity [65,66]. Li et al. successfully fabricated micro-sized nitrate ZnAl Layered Double Hydroxide (...
We certainly have no sectional feelings in the matter, though Lewis has labored hard to impress the public with a contrary belief; and he has even brought false charges of the basest kind against our more respectable citizens, all to draw the attention of the public from the true facts in...
Fig. 1. Design strategies of advanced functional membranes assembled from responsive 2D monatomic lamellas. Thereof, the figure of phase tuning is revised form Ref. [33], and the figure of charge tuning is revised form Ref. [34]. 2.1.1. Size tuning In different humidity conditions, the per...
the size of pyridine is small which enables immediate charge transfer between the support and active sites. It is reasonable to expect that the additional coordination of CoPc with pyridine group will form the Co–N5structure in the Co HSACs and break the charge symmetry of the pristine Co–N...
Two charges 4 cm apart repel each other with a force of 2xx10^(-2)N in air. When a dielectric slab of thickness 1 cm is placed between them, The force is redu
a magnetron is positioned in back of the target to create a larger magnetic field adjacent to the target. The magnetic field traps electrons, and, to maintain charge neutrality in the plasma, the ion density also increases. As a result, the plasma density and sputter rate are increased. The...
