    In the given figure the total charge stored in the combination of capacitors is 100μC100\mu C. The value of ' xx ' is___

  2. Question 2

    Laws of Motion. Asked once: 2021 Paper 23

    Statement I: If three forces F→1,F→2{\overrightarrow{F}}_{1},{\overrightarrow{F}}_{2} and F→3{\overrightarrow{F}}_{3} are represented by three sides of a triangle and F→1+F→2=−F→3{\overrightarrow{F}}_{1}+{\overrightarrow{F}}_{2}= -{\overrightarrow{F}}_{3}, then these three forces are concurrent forces and satisfy the condition for equilibrium. Statement II: A triangle made up of three forces F→1,F→2{\overrightarrow{F}}_{1},{\overrightarrow{F}}_{2} and F→3{\overrightarrow{F}}_{3} as its sides taken in the same order, satisfy the condition for translatory equilibrium. In the light of the above statements, choose the most appropriate answer from the options given below:

    A swimmer wants to cross a river from point AA to point BB. Line ABAB makes an angle of 30∘30^{\circ} with the flow of river. Magnitude of velocity of the swimmer is same as that of the river. The angle θ\theta with the line ABAB should be ____∘\_\_\_\_^{\circ}, so that the swimmer reaches point BB.

  5. Question 5

    Ray Optics. Asked once: 2021 Paper 26

    12
    Given below are two statements: One is labeled as Assertion AA and the other is labeled as Reason R. Assertion A: For a simple microscope, the angular size of the object equals the angular size of the image. Reason R: Magnification is achieved as the small object can be kept much closer to the eye than 25 cm25\text{ }cm and hence it subtends a large angle. In the light of the above statements, choose the most appropriate answer from the options given below:
