Lense Placed At A Distance From Each Other

Two magnets are placed at a distance from each other on a frictionless surface, as shown in the given figure. The magnets will experience

Four metallic plates each with a surface area of one side A are placed at a distance d from each other. The plates are connected as shown in the circuit diagram. Then the capacitance of the system between a and b is

Six metallic plated each with a surface area of one side A. are placed at a distanced d from each other. The alternate plates are connected to points P and Q as shown in figure : The capacitance of the system is :

Four metallic plates each with a surface area A of one side and placed at a distance d from each other. the plates are connected as shown in the fig. Then the capacitance of the system between a and b is -

Two body of same mass 'm' each are placed at distance d from each other, then gravitational force between them is F. If 50% mass is transferred from one body to another and distance between them increased by 50% then new gravitational force between them will be :

Two point charges in air at a distance of 20 cm. from each other interact with a certain force. At what distance from each other should these charges be placed in oil of relative permittivity 5 to obtain the same force of interaction –

Five identical plates of equal area A are placed parallel to each other and at equal distance d from each other as shown in the figure. The effective capacity of the system between the terminals A and B is

Two charges of values 2 muC and -50 muC are placed at a distance of 6 cm from each other. The distance of the point (in cm) from the bigger charge where the electric intensity will be zero is :
