1:40:27 E = 10^5 N/C Torque = 8√3 Nm 2l = 2 × 10^-2 m Angle = 60° q = ? As we know Torque = PEsin theta Torque = 2ql × E sin theta q = Torque / 2l E sin theta On putting all the values , we get q = 8 × 10^-3 C or 8mC 💯

1:39:50 horizontal force acting on Bob = qE F1 = 2 × 10^-8 × 20000 F1 = 4 × 10^-4 N vertical force acting on Bob = mg F2 = 30 × 10^-6 × 10 F2 = 3 × 10^-4 N Tension in the thread will be √ F1^2 + F2^2 F = √ 25 × 10^-8 F = 5 × 10^-4 N 💯

1:40:37 E1 = 50 i E2 = 100 i Theta 1 = 180° Theta 2 = 0° Total flux = E1dscos180° + E2dscos0° = -1/2 + 1 = 1/2 Total flux = 0.5 Nm^2/C💯 Total charge (q) = flux × epsilon not q = 4.425 × 10^-12 C 💯

1:39:24 electric dipole is first placed parallel to electric field , it means angle between dipole and electric field is 0° . Then , it is rotated to 180° . Then workdone in rotating it to 180° = PE (cos theta 1 - cos theta 2 ) = PE ( cos 0° - cos 180° ) = PE [ 1 - (-1) Workdone = 2PE 💯

1:40:00 Here in this question 64 small drops each of charge q constitute to form a larger drop of charge Q Q = 64q To get the ratio of surface charge density we must find the radius of larger drop to get area of larger drop . As we know , volume will be same for total 64 smaller drops and larger drop So, 64 × 4/3 × π r^3 = 4/3 × π R^3 From here we get ,( R = 4r ) Charge density of smaller drop = q / 4πr^2 Charge density of larger drop = 64q / 4 π (4r)^2 Ratio of charge density of smaller drop to charge density of larger drop = 1:4 💯

1:39:04 SOLUTION:- 🔥 Firstly , the two conducting balls are brought in contact so the total charge will be [ -Q + 3Q = 2Q ] and after separation, the charge will be equally distributed so , charge on each ball will be [ 2Q/2 = Q ]. After having same charge they both will repel each other so the force acting between them will be repulsive 💯
